Phosphorylation of the Rpb1 Subunit of Pol II Causes What

Question

Phosphorylation of the Rpb1 subunit of pol II causes what to occur?
A)binding to histone proteins
B)hydrogen bonding with guanine residues near the start of transcription
C)dissociation from the promoter
D)transcription termination
E)none of the above

Accepted Answer

Phosphorylation of the Rpb1 subunit of pol II promotes dissociation of the polymerase from the promoter, allowing for elongation of the transcript. It does not directly affect binding to histones or hydrogen bonding with DNA. It also does not cause transcription termination.
