WebJun 20, 2024 · Silent Mutation Definition. A silent mutation is a change in the sequence of nucleotide bases which constitutes DNA, without a subsequent change in the amino acid or the function of the overall protein. Sometimes a single amino acid will change, but if it has the same properties as the amino acid it replaced, little to no change will happen.

WebIn a nonsense mutation, a change in the genetic code leads to a STOP codon instead of an amino acid codon. Therefore the rest of the protein isn't formed because the translation process is halted early by the STOP codon. WebA deletion mutation is caused by the removal of one or more nucleotides. A deletion of three bases will typically only affect one or two amino acids, but a deletion of one or two bases disrupts all the codons “downstream” of the mutation and affects the entire remaining reading frame of the gene (a frameshift mutation ).
