Answer #1

Ans: Insertion sequence repair is not a DNA repair mechanism.

Direct repair systems act directly on damaged nucleotides, converting each one back to its original structure. Base excision repair and nucleotide excision repair are the types of excision repair in that involves the excision of a segment of the polynucleotide containing a damaged siite. In mismatch repair system can detect mismatches that occure in DNA replication. While insertion excision repair is not example of dna repair mechanism.
