DNA Methylation

Question

DNA methylation
A)increases transcription.
B)inhibits transcription.
C)increases crossover events.
D)decreases crossover events.
E)promotes post-translational modification of proteins.

Accepted Answer

DNA methylation is a process where a methyl group is added to the cytosine bases of DNA, typically at CpG sites. This modification is associated with gene silencing and inhibition of transcription. Therefore, option B is the correct answer.
