The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and a process fundamental to all life. But the inner workings of this ...

RNA helicases are a group of enzymes that bind to and alter RNA in an ATP-dependent way. They play significant roles in RNA metabolism, gene expression regulation, and innate immunity. Different RNA ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...
