DNA is a polymer of nucleotides which are linked to each other by `3'-5'` phosphodiester bond . To prevent polymerisation of nucleotides, which of the following modifications would you choose ?

A

Replace purine with pyrimindines

B

Remove/ Replace 3' OH group in deoxy ribose

C

Remove/Replace2' OH group with some other group in deoxy ribose

D

Both (b) and (c)

Text Solution

Verified by Experts

The correct Answer is:
B

The enzhme called DNA polymerase progressively adds deoxyribonucleotides to the free 3'-end of the growing polynucleotide chain so, that replication of the 3'-5' strand of the DNA molecule is continuous (growth of the new strand in 5`to`3' direction).
