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). WebAug 31, 2011 · Synonymous mutations that affect the kinetics of translation can either slow down the rate of protein synthesis or lead to protein misfolding, which, in turn, can result in proteotoxicity. safti christophe sabyWebMissense 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.
