A Quote by Elizabeth Kolbert

Mitochondrial DNA, which is a sort of abridged version of DNA, is passed directly from mother to child, so it's something that can be looked at to trace matrilineal descent.
The inability to trace DNA to actual diseases has serious consequences. As does the opposite problem - not being able to trace diseases back to DNA.
People are comprised of sets of DNA from each parent. If you looked at just the DNA from your father, it wouldn't tell you who you really are.
We are machines built by DNA whose purpose is to make more copies of the same DNA. ... This is exactly what we are for. We are machines for propagating DNA, and the propagation of DNA is a self-sustaining process. It is every living object's sole reason for living.
Mitochondrial DNA is in higher concentration, lasts longer, and can be extracted from bones.
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.
Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed.
We really invented the genre of tracing family trees and going back as far as we could on the paper trail. When the paper trail disappeared, we used DNA analysis. The technology was just being invented that allowed you to trace ancestry through DNA.
My mother often mailed me articles from 'Reader's Digest' about advances in DNA chemistry. No matter how I tried to explain it to her, she never grasped the concept that I could have been writing those articles, that something I had invented made most of those DNA discoveries possible.
Sequencing DNA on the ISS will enable NASA to see what happens to genetic material in space in real time, rather than looking at a snapshot of DNA before launch and another snapshot of DNA after launch and filling in the blanks.
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.
DNA neither cares nor knows. DNA just is. And we dance to its music.
Private is our DNA, in my DNA. It enables us to make decisions for the long term.
Most organisms have loads of junk DNA - less pejoratively, noncoding DNA - cluttering their cells.
The information in DNA could no more be reduced to the chemical than could the ideas in a book be reduced to the ink and paper: something beyond physics and chemistry encoded DNA.
I would argue that we're not limited by actual DNA. You can re-create the ancient DNA by looking at the genomes of existing animals.
Junk DNA - or, as scientists call it nowadays, noncoding DNA - remains a mystery: No one knows how much of it is essential for life.
