Question

When regions around genes become sensitive to the enzyme DNase I, this is an indication that those regions areA. 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 m

Answer 1

Answer: A. becoming transcriptionally active

Explanation:

Regions that are sensitive to the enzyme DNase I, are regions of chromatin that lost their condensed structure, thereby leaving the DNA accessible and exposed to degradation by  the DNase I enzymes. These Chromatin regions become transcriptionally active .

These regions are referred to as DNase I hypersensitive sites.
