Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches

Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they.....»»

tRNAs help some mRNAs get lost in translation

Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein can be made. They publis.....»»
