<Li> Silent mutations are mutations that do not result in a change to the amino acid sequence of a protein but do change the nucleotide sequence , unless the changed amino acid is sufficiently similar to the original . They may occur in a region that does not code for a protein , or they may occur within a codon in a manner that does not alter the final amino acid sequence . Silent mutations are also called silent substitutions , since they are not palpable changes as the changes in phenotype . The phrase silent mutation is often used interchangeably with the phrase synonymous mutation ; however , synonymous mutations are a subcategory of the former , occurring only within exons ( and necessarily exactly preserving the amino acid sequence of the protein ) . Synonymous mutations occur due to the degenerate nature of the genetic code . There can also be silent mutations in nucleotides outside of the coding regions , such as the introns , because the exact nucleotide sequence is not as crucial as it is in the coding regions . </Li>
