Option A

Option B

Option C

Option D

Solution

For long $DNA$ molecules, since the two strands of $DNA$ cannot be separated in its entire length the replication occur within a small opening of the $DNA$ helix referred to as replication fork.

$=$ The process of copying genetic information from one strand of the $DNA$ into $RNA$ is termed a transcription.
