Question

Quizplus · Accepted Answer

The p300/CBP coactivator proteins are histone acetyltransferases, which means they add acetyl groups to histones. This process alters the structure of chromatin, making it more accessible to transcription factors and RNA polymerase, and thereby remodeling chromatin. Therefore, the correct choice is B, chromatin remodeling.

Answer: C
 The p300/CBP coactivator proteins do play a role in transcription, but they do not directly form the transcription initiation complex or carry out DNA acetylation. Instead, they help recruit RNA polymerase II by altering the structure of chromatin, which is necessary for transcription to occur. Therefore, in this context, the correct choice is C, recruitment of RNA pol II.
