Biologists offer clearer picture of how protein machine systems tweak gene expression
Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case ...

'GPS system' for protein synthesis in nerve cells gives clues for understanding brain disorders
Scientists at the University of Pennsylvania explain how a class of RNA molecules is able to target the genetic building blocks that guide the functioning of a specific part of the nerve cell. Abnormalities at this site are ...

Rett syndrome mobilizes jumping genes in the brain
With few exceptions, jumping genes-restless bits of DNA that can move freely about the genome-are forced to stay put. In patients with Rett syndrome, however, a mutation in the MeCP2 gene mobilizes so-called ...
