Scientists discover precise DNA sequence code critical for turning genes on | KurzweilAI

Molecular biologists at the University of California, San Diego (UC San Diego) have discovered a short sequence of DNA that is essential for turning on (expressing proteins) more than half of all human genes — an achievement that should provide scientists with a better understanding of how human genes are regulated.

Knowing what turns on genes is important. Each human cell contains about six feet of DNA, a double-helical molecular chain containing several billion chemical nucleotides — adenine (A), cytosine (C), guanine (G) and thymine (T) — arranged in a specific sequence, or code.
