Question

The transcriptional state of a cell is irreversible.

(a) True

(b) False

This question was posed to me during an internship interview.

I need to ask this question from Gene Expression Control topic in portion Control of Gene Expression of Cell Biology

Answer 1

The correct answer is:

(b) False

Explanation:

The transcriptional state of a cell is not irreversible. It is dynamic and can be regulated in response to internal and external signals. Gene expression can be turned on or off, and cells can switch between different transcriptional states. This reversible nature allows cells to adapt to changing conditions, a key aspect of processes like differentiation, development, and response to environmental stimuli.
