WebDec 16, 2024 · silent mutation is a synonymous base substitution which does not change the encoded amino acids (this is neutral variation). missense mutation is a non-synonymous bass substitution which changes only one amino acid in the protein (these can affect protein functions but do not always). WebJul 5, 2024 · The melanocytes of wild -type (nonmutant) mice produce more pheomelanin than eumelanin. The result is a sandy -colored mouse. The mutated version of the Mc1r gene, however, triggers melanocyt es to increase the production of eumelanin, resulting in the dark coat -color phenotype. flack v chairperson national crime authorityWebMissense mutations cause a single amino acid change in the protein. Nonsense mutations make a premature "stop" codon. Any codons after that are not translated, and the resulting protein is missing amino acids. Silent mutations code for the same amino acid as before.
