Such circuits have already been used to build a genetic clock and to synthesize cellular machinery that can follow basic logic commands such as AND, OR, and NOR («not OR»). (discovermagazine.com)
To create a genetic clock, Dr. Giniger's team measured the levels of every gene encoded in messenger RNA molecules from cells from the heads and bodies of flies at 3, 10, 30, and 45 days after birth. (sciencedaily.com)
To understand the link between aging and neurodegenerative disorders such as Alzheimer's disease, NIH scientists compared the genetic clocks that tick during the lives of normal and mutant flies. (sciencedaily.com)
