Quotes About Genes

It is no exaggeration to say that genes are essential to nearly every aspect of memory and the process of learning; without them, learning itself would not exist.

Because genes work in combination, the incremental effect of adding a new gene to a genome may be not linear, but exponential.

What Jacob and Monod had discovered, in essence, was that each gene acts like a single line in a computer program.

If there is not preformation, and no blueprint, there is also no getting away from the environment. Genes do not guarantee particular products; rather, they provide particular options: To every gene there is an IF, and with that IF comes an option. In many cases, those options are selected based on cues from the environment, and it is for that reason, more than any other, that the answer to the nature-nurture question is not one or the other, but both.

If you look carefully at our biology after a traumatic experience-all the way down to the way genes are expressed-trauma will change everyone in some way.

It occurred to me that if both genes and environment could produce similar dysfunctional symptoms, the effect of a stressful environment on a person already genetically sensitive to stress would probably be magnified.

Biyoloji sadece deÄŸiÅŸtirilmeyen bir senaryoyu oynayan genlerden ibaret deÄŸildir. Evrimsel süreçlerde olduÄŸu gibi etraftaki dünyaya kar?? da duyarl?d?r.

The science of epigenetics has also made it clear that there are two mechanisms by which organisms pass on hereditary information. Those two mechanisms provide a way for scientists to study both the contribution of nature (genes) and the contribution of nurture (epigenetic mechanisms) in human behavior. If you only focus on the blueprints, as scientists have been doing for decades, the influence of the environment is impossible to fathom. (Dennis 2003; Chakravarti and Little 2003)

a cell is a "programmable chip" whose behavior and genetic activity are primarily controlled by environmental signals, not genes.

over 80 percent of noncoding DNA is involved with regulating the production and assembly of gene-encoded proteins. A major discovery also found that "dark" DNA contains mechanisms by which environmental information can be used to modify the readout of protein-encoding genes. It turns out that dark DNA uses epigenetic mechanisms that enable a human cell with 19,000 gene blueprints to code for over a hundred thousand different protein molecules!

Already there is a study that shows that when humans digest genetically modified foods, the artificially created genes transfer into and alter the character of the beneficial bacteria in the intestine

The team discovered that immune functions in poorer kids had more active inflammatory genes and, simultaneously, expressed more sluggishness in gene networks that control the inflammation response than well-to-do children. The health histories of the poor kids also showed more asthma attacks and other health problems.

Of course there is no doubt that some diseases, like Huntington's chorea, beta thalassemia, and cystic fibrosis, can be blamed entirely on one faulty gene. But single-gene

It is not gene-directed hormones and neurotransmitters that control our bodies and our minds; our beliefs control our bodies and our minds, and thus our lives . . . Oh ye of little belief!

Tanto para los padres adoptivos como para los que no lo son, el mensaje está claro: los genes de tus hijos reflejan sólo su potencial, no su destino.

igual que en las células aisladas, el carácter de nuestra existencia se ve determinado no por nuestros genes, sino por nuestra respuesta a las señales ambientales que impulsan la vida.

The genes for depression cause peoples' brains to overreact to stress.

people who have the genes for unipolar major depression cannot turn off their stress response. When they experience stress from jobs, deadlines, family trouble, medical illness, or extreme excitement, large quantities of steroid stress hormones and norepinephrine come pouring into their brains and cannot be stopped. Every day, this stress overload is fatiguing and killing cells in their brains, bringing on unipolar major depression.

As we've already seen, individual selectionists insist that a creature—be he man or woman or beast—will only sacrifice his comfort if the payback to his genes is greater than what he gives.

Richard Nixon has never been one of my favorite people, anyway. For years I've regarded his very existence as a monument to all the rancid genes and broken chromosomes that corrupt the possibilities of the American Dream; he was a foul caricature of himself, a man with no soul, no inner convictions, with the integrity of a hyena and the style of a poison toad.

While weight loss is important, what's more important is the quality of food you put in your body - food is information that quickly changes your metabolism and genes.

I'm truly blessed with great genes. I've never done anything drastic in my life, and I can proudly say I haven't tried any of those crazy fad diets, either. I believe in eating right and living healthy. Plus, I love going to the gym, and I enjoy yoga because it streamlines your body.

You have little to no response to AAV the first time your body sees it. If you used the same vector twice you would want to bump up immunosuppression. I believe there will be many new ways to deliver genes in the future as well.

Genes are not simple triggers. No one is hardwired to commit murder or any other crime. Our actions are always the result of stupendously complex gene-environment interactions, and environment is likely to remain the more important influence by far.
