A reversion is a mutation that returns a mutant codon back to a codon that gives a wild-type phenotype. At the DNA level, this type of mutation can be an exact reversion or an equivalent reversion. GAG First GTG Exact GAG (glutamic acid) mutation (valine) reversion (glutamic acid) GAG - GTG First Equivalent (valine) reversion GAA (glutamic acid) mutation (glutamic acid) GAG First GTG Equivalent - GAT (glutamic acid) mutation (valine) reversion (aspartic acid) An equivalent reversion produces a protein that is equivalent to the wild type in structure and function. This can occur in two ways. In some cases, the reversion produces the wild-type amino acid (in this case, glutamic acid), but it uses a different codon than the wild-type gene. Alternatively. an equivalent reversion may substitute an amino acid structurally similar to the wild-type amino acid. In our example, an equivalent reversion has changed valine to an aspartic acid. Because aspartic and glutamic acids are structurally…arrow_forwardBelow is the 5’–3’ strand of a double-stranded DNA molecule with the following nucleotide sequences:5’ C C T A T G C A G T G G C C A T A T T C C A A A G C A T A G C 3’ 1.
