WebA frameshift mutation “shifts” how a sequence of nucleotides is read as triplets (codons) during translation. This may, in turn, alter which amino acids are added to polypeptide. In this example, the original reading frame of a gene encodes an mRNA with codons that specify the amino acid sequence: methionine (Met), isoleucine (Ile ...

WebNov 4, 2024 · Frameshift. A reading frame consists of groups of three nucleotides that each code for one amino acid. A frameshift variant occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids. The resulting protein is usually nonfunctional. WebInsertions are mutations in which extra base pairs are inserted into a new place in the DNA. Deletion. Deletions are mutations in which a section of DNA is lost, or deleted. Frameshift. Since protein-coding DNA is divided into codons three bases long, insertions and deletions can alter a gene so that its message is no longer correctly parsed.
