Gene promoters that are tightly wound around a histone complex are easily accessible for RNA polymerase.

Question

Quizplus · Accepted Answer

Gene promoters that are tightly wound around a histone complex are generally inaccessible for RNA polymerase. The histone complex can prevent transcription factors and other regulatory molecules from binding and activating transcription of the gene. In order to initiate transcription, the histone complex must be modified or removed to allow access to the promoter region of the gene.
