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 ...

A team led by Princeton University researchers has developed a tool to peer inside the nucleolus, the cellular compartment responsible for the earliest steps in protein manufacture. This system opens ...

This image illustrates the process of gene transcription within a cell. The DNA double helix unwinds to expose a specific sequence, allowing RNA polymerase to synthesize a complementary pre-mRNA ...

Water molecules play an active, essential role in gene transcription, helping RNA polymerase II carry out the chemical steps ...

The cover of Aging-US Volume 17, Issue 12, features Figure 5 from the research paper, titled "A combination of differential expression and network connectivity analyses identifies a common set of RNA ...
