Final answer:
The T2 termination sequence stops replication forks in an anticlockwise direction.
Step-by-step explanation:
The T2 termination sequence, also known as the ter sequence, stops replication forks in an anticlockwise direction. The ter sequence is a termination signal that helps to end the replication process. The formation of secondary hairpin loop structures near the 3' end of the transcript serves as the termination signal.
