Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

One way to get RNA polymerase going again involves a molecule known as UvrD helicase. Through a series of in vitro and in vivo experiments, Nudler’s team showed how this molecule pulls the ...

DExH/D box proteins are required for the major transactions of RNA, including ... SNF2 and vaccinia virus transcription termination factor NPH-I. NPH-I acts on the RNA polymerase ternary complex ...
