> "The ability to modify specific elements of an organism's genes has
been essential to advance our understanding of biology, including human
health," said Jennifer Doudna, UC Berkeley. "However, the techniques for
making these modifications in animals and humans have been a huge
bottleneck in both research and the development of human therapeutics.
I have not really been following this very closely at all, and don't
understand some basic things about it. Please correct me if I am wrong
in my understanding, but so far, I have just encountered general
statements that leave me with questions.
As I understand it, genes determine the development of the individual
from a single cell. They are present in that cell and also in all the
cells of the resulting organism.
In these gene modification treatments, what genes are being modified?
The genes in some cells, or all cells? If only some cells, how are the
treatments targeted? Are these alterations permanent? Or do they only
last as long as the cell lives
Is there an easy to read primer on this topic?
