A Quote by K. Anders Ericsson
When the human body is put under exceptional strain, a range of dormant genes in the DNA are expressed and extraordinary physiological processes are activated.

Every minute, every second, the pattern of genes being expressed in your brain changes, often in direct or indirect response to events outside the body. Genes are the mechanisms of experience.
.....there are approximately 125 billion miles of DNA in a human body -- your personal DNA is long enough to wrap around the earth 5 million times.
Cancer is really a DNA disease... We have these certain genes that prevent our cells from growing out of control at the expense of the body. And it's a pretty good, robust system. But if a couple of these genes fail, then that's when cancer starts, and cells start growing out of control.
With DNA, you have to be able to tell which genes are turned on or off. Current DNA sequencing cannot do that. The next generation of DNA sequencing needs to be able to do this. If somebody invents this, then we can start to very precisely identify cures for diseases.
It's a very complex network of genes making products which go into the nucleus and turn on other genes. And, in fact, you find a continuing network of processes going on in a very complex way by which genes are subject to these continual adjustments, as you might say - the computer programmer deciding which genes ultimately will work.
Epigenetics doesn't change the genetic code, it changes how that's read. Perfectly normal genes can result in cancer or death. Vice-versa, in the right environment, mutant genes won't be expressed. Genes are equivalent to blueprints; epigenetics is the contractor. They change the assembly, the structure.
Parasites are not only incredibly diverse; they are also incredibly successful. There are parasitic stretches of DNA in your own genes, some of which are called retrotransposons. Many of the parasitic stretches were originally viruses that entered our DNA. Most of them don't do us any harm. They just copy and insert themselves in other parts of our DNA, basically replicating themselves. Sometimes they hop into other species and replicate themselves in a new host. According to one estimate, roughly one-third to one-half of all human DNA is basically parasitic.
I think, as human beings, we at times overvalue the intellect and we undermine the body. I don't mean a body externally and the shape of a body. I mean the intelligence of a body, the memories that a body can store, how a body feels emotion, and how a body processes emotion.
A DNA sequence for the genome of bacteriophage ?X174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.
When the first mechanical clocks were invented, marking off time in crisp, regular intervals, it must have surprised people to discover that time flowed outside their own mental and physiological processes. Body time flows at its own variable rate, oblivious to the most precise hydrogen master clocks in the laboratory. In fact, the human body contains its own exquisite time-pieces, all with their separate rhythms. There are the alpha waves in the brain; another clock is the heart. And all the while tick the mysterious, ruthless clocks that regulate aging.
Exceptional results arrive only when exceptional people put in exceptional effort. It never arises by accident or good fortune.
Mutations can arise anywhere in the genome, in gene DNA and noncoding DNA alike. But mutations to genes have bigger consequences: They can disable proteins and kill a creature.
We as women know that there are no disembodied processes; that all history originates in human flesh; that all oppression is inflicted by the body of one against the body of another; that all social change is built on the bone and muscle, and out of the flesh and blood, of human creators.
The choices you make each day in your diet and lifestyle have a direct influence on how your genetic predisposition is expressed - for better and for worse. You're only as old as your genes, but how your genes are expressed may be modified by exercise, diet and lifestyle choices much more than had previously been believed - and more quickly.
We know that genes shape human cultures and human societies: The DNA we inherited from our ancestors makes certain foods taste better, affects the way we care for children, influences what colors we find vibrant, and contributes to our love of socializing, among other examples.
In the late 1970s, when I was a professor at Caltech, I pioneered four instruments for analyzing genes and proteins that revolutionized modern biology - and one of these, the automated DNA sequencer, enabled the Human Genome Project.
