Dr. Matthew Scott - Jumping Genes: What They Mean for Evolution and Medi..
Δημοσιεύτηκε στις 11 Απρ 2017
The
DNA of one human cell—two copies of our “genome”—would stretch almost
two meters if fully extended. However, normally it’s tightly packaged in
46 chromosomes. About 20,000 genes are distributed along this DNA; they
carry the information for building and operating a human. Any
particular gene is located at a specific place in a chromosome and,
normally, stays there. Carnegie scientist Barbara McClintock discovered,
in corn, that some genes jump from one place in a chromosome to
another. Similar things occur in most organisms, including us. This
discovery, which earned a Nobel prize, led to dramatic advances in
understanding infectious disease, evolution, and the controls that turn
genes on and off in specific places and tissues. This talk will discuss
early life on Earth, how jumping genes may have influenced it, and why
we should care about jumping genes now … for example if you use
antibiotics.
