The replisome, which synthesizes DNA on both leading and lagging strands, always moves toward the replication fork. This must mean that:

#Unit 3. Fundamental Processes

  1. synthesis on the lagging strand requires that the strand fold back onto the replisome.

  2. synthesis on the lagging strand occurs in the 3'-to-5' direction, and synthesis on the leading strand occurs in the 5'-to-3' direction.

  3. synthesis on the leading strand occurs in the 3' to 5' direction, and synthesis on the lagging strand occurs in the 5'-to 3'-direction.

  4. DNA strands are lined up in the same direction, with 3' ends together and 5' ends together.
