If you were to observe the activity of methylated DNA, you would expect it to
A) be replicating nearly continuously.
B) be unwinding in preparation for protein synthesis.
C) have turned off or slowed down the process of transcription.
D) be very actively transcribed and translated.
E) induce protein synthesis by not allowing repressors to bind to it.

Question

Quizplus · Accepted Answer

Methylation of DNA is known to be associated with gene silencing or turning off certain genes. The presence of methyl groups on DNA can prevent the binding of transcription factors and RNA polymerase, which are necessary for transcription to occur. Therefore, observing the activity of methylated DNA would lead you to expect a slowing down or turning off of transcription.
