Frameshift Mutations A frameshift mutation is produced either by insertion or deletion of one or more new bases. Amino acids are the building blocks of proteins, and changes in the sequence of amino acids can result in proteins that don't work properly. Insertion mutations can be small, like in the CAGTC example in which only one nucleotide was inserted, or they can be large, with many nucleotides being added. So, what are nucleotides? Lynn has a BS and MS in biology and has taught many college biology courses. Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. Which number of base pairs in an insertion mutation would cause a frameshift? {{courseNav.course.mDynamicIntFields.lessonCount}} lessons The mutation changes one codon for an amino acid into another codon for that same amino acid.
