The code for survival

When cells are exposed to life-threatening stresses, they take quick action to save themselves. Among other defenses, they start manufacturing proteins that perform critical tasks such as repairing DNA.

Researchers at MIT and the University of Albany have now discovered one way that cells boost production of such proteins. In the Dec. 16 issue of PLoS Genetics, they report that when under stress, cells reprogram a complicated system of chemical modifications of the RNA molecules that read the genetic code and deliver protein building blocks.
