Webpoint - single base change silent - nucleotide change in a wobble base so that it is the same amino acid as before (ex: UCU and UCA both code for serine) missense - single nucleotide change results in a codon that codes for a different amino acid nonsense - point mutation that results in a premature stop codon insertions/deletions - cause a frameshift … WebThe most common nucleotide mutations are substitutions, in which one base is replaced by another. Substitutions can be of two types, either transitions or transversions. Transition substitution refers to a purine or pyrimidine being replaced by a base of the same kind; for example, a purine such as adenine may be replaced by the purine guanine.
