Answer 1

The answer is A. point mutation which does not change the amino acid. A point mutation is a mutation of gene in which a single nucleotide is changed from the sequence. In this case, the  amino acid was replaced by the same amino acid in which there will be no effect on the product of the sequence. This will not alter the replicated DNA, Product that will be produced will be essentially the same.
