It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own ...

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 ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...
