What happens when DNA polymerase replicating DNA encounters RNA polymerase transcribing DNA in the same direction?

What will be an ideal response?


Ans: DNA polymerase is able to move 10× faster than RNA polymerase, so DNA polymerase normally overtakes RNA polymerase. It appears that DNA polymerase bypassing RNA polymerase without disrupting transcription, but the mechanism is unknown.
