Question

As there occurs more and more condensation of chromatin during cell division, there occurs

• A. Increase in heterochromatin
• B. Increase in euchromatin
• C. Differentiation of heterochromatin and euchromatin decreases
• D. Differentiation of heterochromatin and euchromatin increases

Answer 1

Answer:

D. Differentiation of heterochromatin and euchromatin increases

• As cell division progresses and cells enter the mitotic phase, there is an increase in chromatin condensation.

• This increased condensation is associated with the formation of distinct regions of heterochromatin and euchromatin within the chromosomes.

• Heterochromatin refers to the densely packed and transcriptionally inactive regions of chromatin, while euchromatin refers to the less condensed and transcriptionally active parts.

• During mitosis, the chromatin undergoes significant condensation to facilitate proper chromosome segregation and organization.
