Discontinuous synthesis of DNA occurs in one strand, because:
a. DNA molecule being synthesised is very long
b. DNA dependent DNA polymerase catalyses polymerisation only
in one direction (5' → 3')
c. it is a more efficient process
d. DNA ligase joins the short stretches of DNA
The answer is the option (b) DNA dependent DNA polymerase catalyses polymerisation only in one direction (5' -> 3')
