Question

4) In eukaryotic cells, some transcription activators _________. Mark the correct answer(s).

a. direct the hyperacetylation of nucleosomes near a promoter region opens the chromatin structure so as to facilitate the binding of other proteins required for transcription initiation

b. bind to distant enhancers and can interact with transcription factors bound to a promoter because DNA is flexible and the intervening DNA can form a large loop

c. function as auxiliary RNA polymerases thus increasing the overall transcription rate

d. direct the deacetylation of histone N-terminal tails leading to condensation of the DNA

Explanation / Answer

b. bind to distant enhancers and can interact with transcription factors bound to a promoter because DNA is flexible and the intervening DNA can form a large loop
