D

Text Solution

Verified by Experts

The correct Answer is:
d
(d) : Synthesis of DNA by DNA polymerases occurs only in `5' rarr 3'` direction. One strand called leading strand , is copied in the same direction as the unwinding helix. The other strand is known as lagging strand. Replication of lagging strand is in a dicontinuous way , and in the direction of growth of lagging stand is `3' rarr 5'` though in short segments of DNA which are always in the `5' rarr 3'` direction. These short segments are called Okazaki fragments joined together by the action od DNA ligase.
