Answer:
The rule of complimentary base pairing is strictly followed when complimentary stand is synthesized.
Explanation:
During the semi-conservative replication of DNA, the one strand of the original DNA molecule is kept safe and a new strand is synthesized with the help of free nucleotides present there. During the formation of new strand on the original strand, the rule of complimentary base pairing is strictly followed and the nucleotides join to form the new stand according to this rule. Due to this there is less chance that a wrong base pairing will occur and in this way the new stand is formed complimentary to the original strand is free from any mutations.
