Question

Why is replication not continuous on both the templated of replicating DNA molecules?
​

Answer 1

Explanation:

The enzyme responsible for continuous and discontinuous replication of the two strands of a DNA molecule is DNA-dependent DNA polymerase.

This enzyme catalyses the polymerization only in one direction, i.e., from 5' ----> 3'. As a result, on template strand with 3' ----> 5' the replication is continuous while on the template strand with polarity 5' ----> 3' it is discontinuous.
