Hi, the answer of first question is epigenetic regulation.
00:06
Epigenetic regulation involve histone modification, histone modification, modification and dna methylation.
00:23
And dna methylation, they altered the chromatin structure.
00:33
They alter the chromatin structure thereby affecting the assets of dna, affecting the assesses of dna for rna polymerase.
00:54
4 rna polymerase.
01:00
They are headed table.
01:04
It allow the organism to sense change, allow the organism to sense change and adapt to the environment.
01:17
Sense change and adapt to the environment without altering the dna sequence, without altering the dna sequence.
01:33
So according to this, option c is the correct answer.
01:36
The answer of the second question is dna methylation d .n...
