Lucian Webster · Answer 1

A and B is correct.

Explanation:

Mutations are spontaneous variations to nucleotide sequences, therefore in two animals or two chromosomes they can not be identical by nature. Therefore, the introns interact with non-coding sequences and therefore their sequences are not established as consensus in nature and are therefore highly prone to mutations.

Hence both the statement are correct.
