The Okazaki fragments in DNA chain growth:

  1. A
    result in transcription
  2. B
    polymerize in the 3'-to-5' direction and forms replication fork
  3. C
    prove semi-conservative nature of DNA replication
  4. D
    polymerize in the 5'-to-3' direction and explain 3'-to-5' DNA replication

Solution & Step-by-step Explanation

DNA polymerase can only add nucleotides in the direction. On the lagging strand ( direction relative to the fork), replication occurs discontinuously in short segments called Okazaki fragments, each synthesized in the direction.
