Genomes Quotes

The secret to battling cancer, then, is to find means to prevent these mutations from occurring in susceptible cells, or to find means to eliminate the mutated cells without compromising normal growth. The conciseness of that statement belies the enormity of the task. Malignant growth and normal growth are so genetically intertwined that unbraiding the two might be one of the most significant scientific challenges faced by our species. Cancer is built into our genomes: the genes that unmoor normal cell division are not foreign to our bodies, but rather mutated, distorted versions of the very genes that perform vital cellular functions. And cancer is imprinted in our society: as we extend our life span as a species, we inevitably unleash malignant growth (mutations in cancer genes accumulate with aging; cancer is thus intrinsically related to age). If we seek immortality, then so, too, in a rather perverse sense, does the cancer cell. ~ Siddhartha Mukherjee

Databases, ontologies, and visual representations tie informatic genomes to the specific practices of computers, computational biology, and bioinformatics. ~ Anonymous

Every single cancer is a genetic disease. Not necessarily inherited from your parents, but it's genetic changes which cause cancer. So as we sequence the genomes of tumours and compare those to the sequence of patients, we're getting down to the fundamental basis of each individual person's cancer. ~ Craig Venter

In the future, a new generation of artists will be writing genomes as fluently as Blake and Byron wrote verses. ~ Freeman Dyson

In an age of molecular genomics, it is ever more apparent that the fingerprints of evolution are pressed deeply into human DNA, just as they are into the genomes of every other organism. Biologists understand this, and so do students who study the science of life. ~ Kenneth R. Miller

By comparing the human and chimp genomes, we can see the process of evolution clearly in the changes (in DNA) since we diverged from our common ancestor. ~ Bob Waterston

One of the most essential and mundane of human activities - taking care of children - requires high levels of anxious vigilance ... [Parents] dare not risk assuming that the sudden quiet from the toddlers' room means they are studying with Baby Einstein. Visualize fratricidal stranglings and electric outlets stabbed with forks: this is how we have reproduced our genomes. ~ Barbara Ehrenreich

(The genomes of two individual humans differ by an average of about 3 million positions, which is approximately 0.1 percent of the total. Most of these are single base changes or changes in tandem repeat lengths.) ~ George M. Church

We need 10,000 genomes, not 100, to start to understand the link between genetics, disease and wellness. ~ Craig Venter

Understanding how Cas9 is able to locate specific 20-base-pair target sequences within genomes that are millions to billions of base pairs long may enable improvements to gene targeting and genome editing efforts in bacteria and other types of cells. ~ Jennifer Doudna

We have Borna virus genes. We're part Borna virus, which is weird, but apparently our cells and our genomes in a weird way might actually be grabbing these viruses, grabbing genetic material from the viruses that are infecting it and pulling them into their own genome. ~ Carl Zimmer

Even if we have a reliable criterion for detecting design, and even if that criterion tells us that biological systems are designed, it seems that determining a biological system to be designed is akin to shrugging our shoulders and saying God did it. The fear is that admitting design as an explanation will stifle scientific inquiry, that scientists will stop investigating difficult problems because they have a sufficient explanation already.

But design is not a science stopper. Indeed, design can foster inquiry where traditional evolutionary approaches obstruct it. Consider the term "junk DNA." Implicit in this term is the view that because the genome of an organism has been cobbled together through a long, undirected evolutionary process, the genome is a patchwork of which only limited portions are essential to the organism. Thus on an evolutionary view we expect a lot of useless DNA. If, on the other hand, organisms are designed, we expect DNA, as much as possible, to exhibit function. And indeed, the most recent findings suggest that designating DNA as "junk" merely cloaks our current lack of knowledge about function. For instance, in a recent issue of the Journal of Theoretical Biology, John Bodnar describes how "non-coding DNA in eukaryotic genomes encodes a language which programs organismal growth and development." Design encourages scientists to look for function where evolution discourages it.

Or consider vestigial organs that later are found t ~ William A. Dembski

In agriculture, people have taken wild plants that can't be eaten by people - and turned them into wonderful food sources. And that's because genomes can change, and people working with plants have picked mutations. Mutations are nothing more than genetic changes. ~ Nina Fedoroff

My father and I made genetics history. We were the first African-Americans and the first father and son anywhere to have their genomes sequenced. ~ Henry Louis Gates

Africans carried more genetic diversity within their genomes than non-Africans, as a simple result of the fact that humanity had originated on that continent and spread outward. Non-African races had been founded by isolated groups of adventurers. Breeding among themselves, they had created gene pools that were necessarily limited to what they had brought with them: only a subset of what was to be found in Africa. This idea had been used to explain, for example, why Africa contained both the tallest and the most diminutive people in the world, and why so many top athletes were African. It wasn't because they were naturally better athletes but because the bell-shaped curve of random genetic variation was wider. ~ Neal Stephenson

Mutants are necessary to maintain the essence of our selves. Our genomes has negotiated a fragile balance between counterpoised forces, pairing strand with opposite strand, mixing past and future, pitting memory against desire. It is the most human of all things that we possess. Its stewardship may be the ultimate test of knowledge and discernment of our species. ~ Siddhartha Mukherjee

One of the things about genetics that has become clearer as we've done genomes - as we've worked our way through the evolutionary tree, including humans - is that we're probably much more genetic animals than we want to confess we are. ~ Craig Venter

History repeats itself, in part because the genome repeats itself. And the genome repeats itself, in part because history does. The impulses, ambitions, fantasies, and desires that drive human history are, at least in part, encoded in the human genome. And human history has, in turn, selected genomes that carry these impulses, ambitions, fantasies, and desires. This self-fulfilling circle of logic is responsible for some of the most magnificent and evocative qualities in our species, but also some of the most reprehensible. It is far too much to ask ourselves to escape the orbit of this logic, but recognizing its inherent circularity, and being skeptical of its overreach, might protect the week from the will of the strong, and the 'mutant' from being annihilated by the 'normal'. ~ Siddhartha Mukherjee

Once we all have our genomes, some of these extremely rare diseases are going to be totally predictable. ~ Craig Venter

In 2006, the Vogelstein team revealed the first landmark sequencing effort by analyzing thirteen thousand genes in eleven breast and colon cancers. (Although the human genome contains about twenty thousand genes in total, Vogelstein's team initially had tools to assess only thirteen thousand.) In 2008, both Vogelstein's group and the Cancer Genome Atlas consortium extended this effort by sequencing hundreds of genes of several dozen specimens of brain tumors. As of 2009, the genomes of ovarian cancer, pancreatic cancer, melanoma, lung cancer, and several forms of leukemia have been sequenced, revealing the full catalog of mutations in each tumor type. Perhaps ~ Siddhartha Mukherjee

Jonathan Sacks; "One way is just to think, for instance, of biodiversity. The extraordinary thing we now know, thanks to Crick and Watson's discovery of DNA and the decoding of the human and other genomes, is that all life, everything, all the three million species of life and plant life - all have the same source. We all come from a single source. Everything that lives has its genetic code written in the same alphabet. Unity creates diversity. So don't think of one God, one truth, one way. Think of one God creating this extraordinary number of ways, the 6,800 languages that are actually spoken. Don't think there's only one language within which we can speak to God. The Bible is saying to us the whole time: Don't think that God is as simple as you are. He's in places you would never expect him to be. And you know, we lose a bit of that in English translation. When Moses at the burning bush says to God, "Who are you?" God says to him three words: "Hayah asher hayah."Those words are mistranslated in English as "I am that which I am." But in Hebrew, it means "I will be who or how or where I will be," meaning, Don't think you can predict me. I am a God who is going to surprise you. One of the ways God surprises us is by letting a Jew or a Christian discover the trace of God's presence in a Buddhist monk or a Sikh tradition of hospitality or the graciousness of Hindu life. Don't think we can confine God into our categories. God is bigger than religion. ~ Krista Tippett

RNA viruses are limited to small genomes because their mutation rates are so high, and their mutation rates are so high because they're limited to small genomes. In fact, there's a fancy name for that bind: Eigen's paradox. Manfred Eigen is a German chemist, a Nobel winner, who has studied the chemical reactions that yield self-organization of longer molecules, a process that might lead to life. His paradox describes a size limit for such self-replicating molecules, beyond which their mutation rate gives them too many errors and they cease to replicate. They die out. RNA ~ David Quammen

If there is a race, it is one to bring the benefits of genomes to human therapeutics. We all want to get there. We all want people to have much more meaningful and productive lives as they age. ~ Craig Venter

We carry stores of DNA in our nuclei that may have come in, at one time or another, from the fusion of ancestral cells and the linking of ancestral organisms in symbiosis. Our genomes are catalogues of instructions from all kinds of sources in nature, filed for all kinds of contingencies. ~ Lewis Thomas

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

We're at the point where we don't need one genome or just a few genomes to interpret your genome. We need tens of thousands of genomes as a starting point, coupled with everything we can know about their physiology. It's only when we do that giant computer search, putting all that DNA together, that we will be able to make sense in a meaningful statistical manner of what your DNA is telling you. We're just at the start of trying to do that. ~ Anonymous

How does the body push the comparatively tiny genome so far? Many researchers want to put the weight on learning and experience, apparently believing that the contribution of the genes is relatively unimportant. But though the ability to learn is clearly one of the genome's most important products, such views overemphasize learning and significantly underestimate the extent to which the genome can in fact guide the construction of enormous complexity. If the tools of biological self-assembly are powerful enough to build the intricacies of the circulatory system or the eye without requiring lessons from the outside world, they are also powerful enough to build the initial complexity of the nervous system without relying on external lessons.

The discrepancy melts away as we appreciate the true power of the genome. We could start by considering the fact that the currently accepted figure of 30,000 could well prove to be too low. Thirty thousand (or thereabouts) is, at press time, the best estimate for how many protein-coding genes are in the human genome. But not all genes code for proteins; some, not counted in the 30,000 estimate, code for small pieces of RNA that are not converted into proteins (called microRNA), of "pseudogenes," stretches of DNA, apparently relics of evolution, that do not properly encode proteins. Neither entity is fully understood, but recent reports (from 2002 and 2003) suggest that both may play some role in the all-important process of regul ~ Gary F. Marcus
