Question

Which of the following address(es) the problems posed by chromatin during transcription?

a. In some instances, protein factors can interfere with chromatin structure at specific locations, opening sensitive sites.
b. The action of chromatin remodeling factors is involved, which require ATP hydrolysis to allow the promoter regions to accept the complex.
c. In some cases, chromatin structure rearranges at the time of replication.
d. All of the listed statements are true.

Answer 1

d. All of the listed statements are true.

Step-by-step explanation:

Chromatin is presnet in the chromosome consist of protein and protein. histones are themajor proteins in chromatin that help in the compact packaging of the DNA in the cell nucleus.

There are several problems posed by chromatin during transcription:

• During transcription, protein can interfere with the chromatin structure at specific locations and interefere with its structure.
• Histone post-translation modifications (PTMs) regulate the structure of chromatin and also guide the remodeling enzymes which use the energy derived from ATP hydrolysis to reposition nucleosomes.
• During replication the chromatin structure rearrange itself in order to make the new DNA fit inside the nucleus.

Hence, the correct option is d.
