WebWhat happens when a substitution mutation occurs? there are four possible outcomes 1. the amino acid sequence of the protein may be unchanged 2. the amino acid sequence may be altered, but protein function is essentially unchanged 3. Protein function may be changed by an altered amino acid sequence WebOct 17, 2007 · The moniker “silent” to describe a synonymous mutation or SNP comes from Anfinsen's principle that the amino acid sequence of a protein alone determines the three-dimensional structure of a protein and, hence, its function. Genetic and biochemical studies have, however, suggested for a long time that such a view may be too simplistic. descargar wave live 3d

How do silent mutations affect a protein

WebMutations that do not result in a change in the amino acid sequence of the protein are referred to as silent mutations.
