RNA polymerase in action. The three stages of transcription involve various functions of RNA polymerase that result in the synthesis of RNA: 1. Initiation begins when RNA polymerase wraps around the ...

The influenza virus polymerase transcribes or replicates the segmented RNA genome (viral RNA) into viral messenger RNA or full-length copies. To initiate RNA synthesis, the polymerase binds to the ...

Cryo-EM and X-ray crystallography to determine the mammalian RNA Pol II–DSIF complex structure maps DSIF's polymerase, DNA-template and transcript contacts that facilitate transcription elongation.
