Restriction enzymes are palindromic; that is, they read the same in the 5\' to 3

Question

Restriction enzymes are palindromic; that is, they read the same in the 5' to 3' direction on each strand of DNA.

What is the advantage for bacteria of having restriction sites organized in this way?

A. Presence of palindromic sequences in DNA enhances the likelihood of faultless replication.

B. Palindromic design of restriction sites allows for more chances of DNA recovery, providing a more reliable DNA repair system.

C. Bacteria defend from restriction enzymes by protective methylation of target sequences. In order for both strands to be methylated, the sequence must be palindromic.

D. Palindromic design of restriction sitees facilitates evolution by allowing alternative combinations of base sequences to be formed after the action of DNA ligase.

Explanation / Answer

Presence of palindromic sequences in DNA enhances the likelihood of faultless replication.
