Secrets of the Longest-Living Mammal Revealed


Secrets of the Longest-Living Mammal Revealed

The genome of the bowhead whale was released this week by scientists who say that it may hold the key to longer and healthier lives for humans. The bowhead whale is the largest animal whose genome has been sequenced. It lives longer than any other mammal, with a lifespan of up to 200 years. Scientists studying its genome found significant differences in genes related to cell cycle, DNA repair, and aging process compared to other mammals. Although it has about 1,000 times as many cells as a human, its cells have a far more efficient anti-tumor response. More… Discuss

ENDOGENOUS RETROVIRUS


Endogenous Retrovirus

Retroviruses carry their genetic blueprint in the form of RNA, which they use to synthesize DNA—the reverse of the usual process. This makes it possible for their genetic material to become a permanent part of the genes of an infected cell. An endogenous retrovirus is a retrovirus-like sequence found in an organism’s genome that is thought to constitute the remains of a true retrovirus absorbed through evolution. In humans, endogenous retroviruses are suspected of involvement in what diseases?More… Discuss
