Which one of the following does not contribute to the activation of transcription in eurkaryotes?

Question

Quizplus · Accepted Answer

Histone deacetylases are enzymes that remove acetyl groups from histone proteins, leading to a more condensed chromatin structure that represses transcription. Thus, they do not contribute to the activation of transcription in eukaryotes. The other choices (A, B, C, and E) all contribute to activation of transcription either by opening up the chromatin structure or modifying the histones to make the DNA more accessible to transcription factors.
