Question

Molecular biologists can determine experimentally whether a region of DNA contains closed chromatin or open chromatin by assessing the sensitivity of the region to Molecular biologists can determine experimentally whether a region of DNA contains closed chromatin or open chromatin by assessing the sensitivity of the region to nucleosomes. b.RNA polymerase II.c. methyltransferase. DNAse. d.histone deacetylase.

Answer 1

c) methyltransferase. DNAse.

Step-by-step explanation:

The way DNA is folded can affect gene expression, or which genes are turned on. When the chromosomes are tightly condensed, the DNA is wrapped very tightly which makes it difficult for transcription factors to bind to the DNA.
