Since my high school years, I have been interested in history, especially in Roman history, a topic on which I have read rather extensively. The Latin that goes with this kind of interest proved useful when I had to generate a few terms and names for cell biology. ~ George Emil Palade
Molecular And Cell Biology quotes by George Emil Palade
All of today's DNA, strung through all the cells of the earth, is simply an extension and elaboration of [the] first molecule. ~ Lewis Thomas
Molecular And Cell Biology quotes by Lewis Thomas
Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria's effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What's more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so. ~ Michael J. Behe
Molecular And Cell Biology quotes by Michael J. Behe
The evolutionists, piercing beneath the show of momentary stability, discovered, hidden in rudimentary organs, the discarded rubbish of the past. They detected the reptile under the lifted feathers of the bird, the lost terrestrial limbs dwindling beneath the blubber of the giant cetaceans. They saw life rushing outward from an unknown center, just as today the astronomer senses the galaxies fleeing into the infinity of darkness. As the spinning galactic clouds hurl stars and worlds across the night, so life, equally impelled by the centrifugal powers lurking in the germ cell, scatters the splintered radiance of consciousness and sends it prowling and contending through the thickets of the world. ~ Loren Eiseley
Molecular And Cell Biology quotes by Loren Eiseley
The history of the knowledge of the phenomena of life and of the organized world can be divided into two main periods. For a long time anatomy, and particularly the anatomy of the human body, was the a and ? of scientific knowledge. Further progress only became possible with the discovery of the microscope. A long time had yet to pass until through Schwann the cell was established as the final biological unit. It would mean bringing coals to Newcastle were I to describe here the immeasurable progress which biology in all its branches owes to the introduction of this concept of the cell. For this concept is the axis around which the whole of the modem science of life revolves. ~ Paul R. Ehrlich
Molecular And Cell Biology quotes by Paul R. Ehrlich
A nutritive centre, anatomically considered, is merely a cell, the nucleus of which is the permanent source of successive broods of young cells, which from time to time fill the cavity of their parent, and carrying with them the cell wall of the parent, pass off in certain directions, and under various forms, according to the texture or organ of which their parent forms a part. ~ John Goodsir
Molecular And Cell Biology quotes by John Goodsir
Biology doesn't know in advance what the end product will be; there's no Stuffit Compressor to convert a human being into a genome. But the genome itself is very much akin to a compression scheme, a terrifically efficient description of how to build something of great complexity-perhaps more efficient than anything yet developed in the labs of computer scientists (never mind the complexities of the brain, there are trillions of cells in the rest of the body, and they are all supervised by the same 30,000-gene genome). And although there is no counterpart in nature to a program that compresses a picture into a compact description, there is a natural counterpart to the program that decompresses the compressed encoding, and that's the cell. Genome in, organism out. Through the logic of gene expression, cells are self-regulating factories that translate genomes into biological structure. ~ Gary F. Marcus
Molecular And Cell Biology quotes by Gary F. Marcus
The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled. It is from the progeny of this parent cell that we take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is a family resemblance. ~ Lewis Thomas
Molecular And Cell Biology quotes by Lewis Thomas
It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism ~ Dennis Flanagan
Molecular And Cell Biology quotes by Dennis Flanagan
The most essential prediction of Darwinism is that, given an astronomical number of chances, unintelligent processes can make seemingly-designed systems, ones of the complexity of those found in the cell. ID specifically denies this, predicting that in the absence of intelligent input no such systems would develop. So Darwinism and ID make clear, opposite predictions of what we should find when we examine genetic results from a stupendous number of organisms that are under relentless pressure from natural selection. The recent genetic results are a stringent test. The results: 1) Darwinism's prediction is falsified; 2) Design's prediction is confirmed. ~ Michael J. Behe
Molecular And Cell Biology quotes by Michael J. Behe
The extracellular genesis of cells in animals seemed to me, ever since the publication of the cell theory [of Schwann], just as unlikely as the spontaneous generation of organisms. These doubts produced my observations on the multiplication of blood cells by division in bird and mammalian embryos and on the division of muscle bundles in frog larvae. Since then I have continued these observations in frog larvae, where it is possible to follow the history of tissues back to segmentation. ~ Robert Remak
Molecular And Cell Biology quotes by Robert Remak
The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life. ~ Linus Pauling
Molecular And Cell Biology quotes by Linus Pauling
A tissue is evidently an enduring thing. It's functional and structural conditions become modified from moment to moment. Time is really the fourth dimension of living organisms. It enters as part into the constitution of a tissue. Cell colonies, or organs, are events which progressively unfold themselves. They must be studied like history. ~ Alexis Carrel
Molecular And Cell Biology quotes by Alexis Carrel
A major push is under way to figure out the molecular basis of those "critical" or "sensitive" periods, to figure out how the brain changes as certain learning abilities come and go. In some, if not all, of those mammals that have the alternating stripes in the visual cortex known as ocular dominance columns, those columns can be adjusted early in development, but not in adulthood. A juvenile monkey that has one eye covered for an extended period of time can gradually readjust its brain wiring to favor the open eye; an adult monkey cannot adjust its wiring. At the end of a critical period, a set of sticky sugar-protein hybrids known as proteoglycans condenses into a tight net around the dendrites and cell bodies of some of the relevant neurons, and in so doing those proteoglycans appear to impede axons that would otherwise be wriggling around as part of the process of readjusting the ocular dominance columns; no wriggling, no learning. In a 2002 study with rats, Italian neuroscientist Tommaso Pizzorusso and his colleagues dissolved the excess proteoglycans with an antiproteoglycan enzyme known as "chABC," and in so doing managed to reopen the critical period. After the chABC treatment, even adult rats could recalibrate their ocular dominance columns. ChABC probably won't help us learn second languages anytime soon, but its antiproteoglycan function may have important medical implications in the not-too-distant future. Another 2002 study, also with rats, showed that chABC can ~ Gary F. Marcus
Molecular And Cell Biology quotes by Gary F. Marcus
For it is not cell nuclei, not even individual chromosomes, but certain parts of certain chromosomes from certain cells that must be isolated and collected in enormous quantities for analysis; that would be the precondition for placing the chemist in such a position as would allow him to analyse [the hereditary material] more minutely than [can] the morphologists ... For the morphology of the nucleus has reference at the very least to the gearing of the clock, but at best the chemistry of the nucleus refers only to the metal from which the gears are formed. ~ Theodor Boveri
Molecular And Cell Biology quotes by Theodor Boveri
I went into science, ending up with a Ph.D. in cell biology, but along the way I found out that experimental science involves many hours and days and nights of laboratory work, which is a lot like washing dishes, only a little more challenging. I was too impatient, and maybe a little too sloppy, for it. ~ Barbara Ehrenreich
Molecular And Cell Biology quotes by Barbara Ehrenreich
In 1973, I left the Rockefeller University to join the Yale University Medical School. The main reason for the move was my belief that the time had come for fruitful interactions between the new discipline of Cell Biology and the traditional fields of interest of medical schools, namely Pathology and Clinical Medicine. ~ George Emil Palade
Molecular And Cell Biology quotes by George Emil Palade
I have a Ph.D. in cell biology. And that's really manual labor. I mean, experimental science, you do it with your hands. So it's very different. You're out there in a lab, cleaning test tubes, and it just wasn't that fascinating. ~ Barbara Ehrenreich
Molecular And Cell Biology quotes by Barbara Ehrenreich
Because the great beauty of embryo development, the bit that human beings find so hard to grasp, is that it is a totally decentralised process ... no cell need wait for instructions from authority; every cell can act on its own information and the signals it receives from its neighbours. We do not organise societies that way ... Perhaps we should try. ~ Matt Ridley
Molecular And Cell Biology quotes by Matt Ridley
What politicians do not understand is that [Ian] Wilmut discovered not so much a technical trick as a new law of nature. We now know that an adult mammalian cell can fire up all the dormant genetic instructions that shut down as it divides and specializes and ages, and thus can become a source of new life. You can outlaw technique; you cannot repeal biology.
Writing after Wilmut's successful cloning of the sheep, Dolly, that research on the cloning of human beings cannot be suppressed. ~ Charles Krauthammer
Molecular And Cell Biology quotes by Charles Krauthammer
Some cultural phenomena bear a striking resemblance to the cells of cell biology, actively preserving themselves in their social environments, finding the nutrients they need and fending off the causes of their dissolution. ~ Daniel Dennett
Molecular And Cell Biology quotes by Daniel Dennett
The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral. ~ Ernst Haeckel
Molecular And Cell Biology quotes by Ernst Haeckel
Kauffman was in awe when he realized all this. Here it was again: order. Order for free. Order arising naturally from the laws of physics and chemistry. Order emerging spontaneously from molecular chaos and manifesting itself as a system that grows. The idea was indescribably beautiful.

But was it life? Well no, Kauffman had to admit, not if you meant life as we know it today. An autocatalytic set would have had no DNA, no genetic code, no cell membrane. In fact, it would have had no real independent existence except as a haze of molecules floating around in some ancient pond. If an extraterrestrial Darwin had happened by at the time, he (or it) would have been hard put to notice anything unusual. Any given molecule participating in the autocatalytic set would have looked pretty much like any other molecule. The essence was not to be found in any individual piece of the set, but in the overall dynamics of the set: its collective behavior. ~ M. Mitchell Waldrop
Molecular And Cell Biology quotes by M. Mitchell Waldrop
Stem cells have the potential to be used to treat and better understand some of the world's most deadly and disabling diseases. ~ Mark Udall
Molecular And Cell Biology quotes by Mark Udall
The hypothesis of molecular vortices is defined to be that which assumes - that each atom of matter consists of a nucleus or central point enveloped by an elastic atmosphere, which is retained in its position by attractive forces, and that the elasticity due to heat arises from the centrifugal force of those atmospheres revolving or oscillating about their nuclei or central points.According to this hypothesis, quantity of heat is the vis viva of the molecular revolutions or oscillations. ~ William John Macquorn Rankine
Molecular And Cell Biology quotes by William John Macquorn Rankine
If you're born in a cubicle and grow up in a corridor, and work in a cell, and vacation in a crowded sun-room, then coming up into the open with nothing but sky over you might just give you a nervous breakdown. ~ Isaac Asimov
Molecular And Cell Biology quotes by Isaac Asimov
A - ris - ta?" Degan asked, sounding horse. "What is it?"
"A rat bit me," she said, once again shocked by her own rasping voice.
"Jasper does that if - " Gaunt coughed and hacked. After a moment, he
spoke again. "If he thinks you're dead or too weak to fight."
"Jasper?"
"I call him that, but I've also named the stones in my cell."
"I only counted mine," Arista said.
"Two hundred and thirty-four," Degan replied instantly.
"I have two hundred and twenty-eight."
"Did you count the cracked ones as two?"
"No. ~ Michael J. Sullivan
Molecular And Cell Biology quotes by Michael J. Sullivan
if I were a gambling addict, then a large portion of my life energy - my time, my thoughts and emotions - would be spent either gambling or fighting my urge to gamble. But for our purposes. feeding my addiction and fighting it are really the same thing. Whether my gambling demon is beating me or I'm beating it doesn't matter. all that matters is that I'm sitting in my prison cell fully engaged in processes that will never move me one inch closer to liberation. That's what demons do. They're like Maya's army of winged monkeys. They always fight a delaying action that expends our resources and prevents us from making forward progress. That's their objective, to occupy us. not to defeat us. ~ Jed McKenna
Molecular And Cell Biology quotes by Jed McKenna
A huge cloud of dust is not a beautiful thing to look at. Very few painters have done portraits of huge clouds of dust or included them in their landscapes or still lifes. Film directors rarely choose huge clouds of dust to play the lead roles in romantic comedies, and as far as my research has shown, a huge cloud of dust has never placed higher than twenty-fifth in a beauty pageant. Nevertheless, as the Baudelaire orphans stumbled around the cell, dropped each half of the battering ram and listening to the sound of crows flying in circles outside, they stared at the huge cloud of dust as if it were a thing of great beauty. ~ Lemony Snicket
Molecular And Cell Biology quotes by Lemony Snicket
If they're in cell block 1A or 1B, these prisoners - they're murderers, they're terrorists, they're insurgents. Many of them probably have American blood on their hands. And here we're so concerned about the treatment of those individuals. ~ James Inhofe
Molecular And Cell Biology quotes by James Inhofe
For the most part I have been able to meet all my goals, but I always strive for bigger goals in life so everything's not complete just yet. My first aspiration was to be known as a singer and also as an advocate for sickle cell disease. I try to be that inspiration, you know. It's not as bad as people try to make it seem. I mean, it is, but it's not. People don't have to be afraid of it; they don't have to be held down by it. Try to find triumph in the situation. ~ A. J. Green
