Question

In the chromatin of interphase chromosomes, regions of the chromosome that contain genes being expressed are generally more compact, while those that contain quiescent genes are more generally more extended.

a-true
b-false

Answer 1

In interphase, eukaryotic chromosomes have two distinct regions known as heterochromatin and euchromatin. Heterochromatin contains genes that are not expressed, while euchromatin contains genes that are transcribed. Hence the correct answer is option B

Step-by-step explanation:

In interphase, eukaryotic chromosomes have two distinct regions that can be distinguished by staining. The tightly packaged region is known as heterochromatin, and the less dense region is known as euchromatin. Heterochromatin usually contains genes that are not expressed, and is found in the regions of the centromere and telomeres. The euchromatin usually contains genes that are transcribed, with DNA packaged around nucleosomes but not further compacted.

Hence the correct answer is option B
