A Site (RNA Polymerase) Definition

  • Site the incoming nucleotide occupies during phosphodiester formation..

    Molecular Biology by Robert F. Weaver



A Site (RNA Polymerase) Explanation

A' site in the RNA polymerase is an active site of the RNA polymerase, where the phosphodiester-bond is formed during transcription. In the growing RNA chain, the 3'-hydroxyl group attacks the 'α-phosphate' of the incoming 'nucleoside triphosphate'.
