When two nucleotides are reversed during DNA replication, it can cause a mutation. In this case, the incorrect copy of the DNA strand will add tyrosine instead of isoleucine when it is translated into protein, option C is correct.
When two nucleotides are reversed during DNA replication, it can result in a mutation. In this case, the original DNA strand has the sequence ATGATT, but the incorrect copy has the sequence ATGTAT. This mutation changes the third nucleotide, so instead of coding for the amino acid isoleucine, it codes for the amino acid tyrosine. Therefore, when the replicated DNA strand is translated into protein, the incorrect copy will add tyrosine instead of isoleucine, option C is correct.
