WebSep 4, 2024 · A frameshift mutation is a deletion or insertion of one or more nucleotides that changes the reading frame of the base sequence. Deletions remove nucleotides, and insertions add nucleotides. Consider the following sequence of bases in RNA: AUG-AAU-ACG-GCU = methionine-asparagine-threonine-alanine WebDue to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier … resitivitychatWebJul 1, 2024 · This single missing or added nucleotide causes a frameshift mutation which throws off the entire reading frame of the amino acid sequence and mixes up the codons. This usually does affect the amino acids that are coded for and change the resulting protein that is expressed. resit in english spelling
