When regions around genes become sensitive to the enzyme DNase I, this is an indication that those regions are:
A) becoming transcriptionally active.
B) becoming more condensed.
C) binding to the single-strand binding proteins.
D) destabilizing and transcriptionally inactive.
E) becoming highly methylated by a methylase.

Question

Quizplus · Accepted Answer

DNase I sensitivity indicates that chromatin is in an open, less condensed state, allowing transcription factors and RNA polymerase to access the DNA, thus making the region transcriptionally active.
