Question

Discontinuous synthesis of DNA occurs in one strand, because:
a. DNA molecule being synthesised is very long
b. DNA dependent DNA polymearse catalyses polymerisation only
in one direction (5’ → 3’)
c. it is a more efficient process
d. DNA ligase has to have a role

Answer 1

Discontinuous synthesis of DNA occurs in one strand, because:
b. DNA dependent DNA polymearse catalyses polymerisation only
in one direction (5’ → 3’)

Answer 2

discontinuous synthesis of DNA occurs in one strand because DNA dependent DNA polymerase catalyzes polymerization only in One Direction.

Option B

Explanation:

• the DNA dependent DNA polymerase is responsible for the polymerization of the DNA strand.the replication of DNA is a complex kept that takes place in the prophase of the cell cycle.

• As a result of this during the DNA replication face the DNA is synthesized from 5to 3 direction .

• as a result of the DNA strand in one of the two strands is discontinuous and it is joint from time to time by using different enzymes.
