Researchers describe mechanism central to maintaining healthy protein levels, avoiding disease states

A new scientific study conducted by a team of leading geneticists has characterized how cells know when to stop translating DNA into proteins, a critical step in maintaining healthy protein levels and cell function. In the study published in Cell, researchers studied short pieces of genetic material called messenger RNA, or mRNA, that serve as a go-between a person's DNA and the proteins it encodes. Researchers were searching for insight into a cellular mechanism that has been a mystery – how do cells sense it is time to stop making mRNA and coordinate cellular machinery to shut down the process?
