Which of the following statements correctly describes the difference between the leading strand and the lagging strand in DNA replication?

#Unit 3. Fundamental Processes
  1. The leading strand is synthesized in the 3' → 5' direction in a discontinuous fashion, while the lagging strand is synthesized in the 5' → 3' direction in a continuous fashion.

  2. The leading strand is synthesized continuously in the 5' → 3' direction, while the lagging strand is synthesized discontinuously in the 5' → 3' direction.

  3. The leading strand requires an RNA primer, whereas the lagging strand does not.

  4. There are different DNA polymerases involved in elongation of the leading strand and the lagging strand.
