Silent Mutation

Explanation:

Silent mutations are errors in DNA replication that do not cause a change in the amino acid sequence. For example, the codon UCU might accidentally be translated as UCC, but both codons call for the amino acid serine, so no disruptions in the formation of the protein occur. It is still a mutation in the DNA, but the mutation doesn't change the ultimate structure of the protein and won't have any effect on its function. Therefore, it is "silent"
