Question

Mention the direction in which:
(a) the leading strand is synthesised.
(b) discontinuous synthesis of DNA occurs.

Answer 1

Answer:

Explanation:

DNA POLYMERASE ENZYMES WHICH HELPS IN MAKING THE DAUGHTER STRAND DURING REPLICATION CA MAKE THE NEW STRANDS ONLY IN 5'-3' DIRECTION.

(1) LEADING STRAND IS MADE IN 5'-3' DIRECTION.

(2) LAGGING STRAND OR DISCONTINUOUS STRAND ARE ALSO MADE IN 5'-3' DIRECTION BUT ARE NOT MADE CONTINOUSLY . THE FRAGMENTS MADE INITIALLY ARE LATER JOINED BY DNA LIGASE ENZYME.

HOPE THIS HELPS.
