They can occur due to deamination of cytosine or because bases have both a common and a rare tautomer. They can be classified as transitions or transversion depending on the similarity of the new base to the old one. It is debatable whether frame-shift belongs to this category, but silent and missense definitely do, and the first discovered one was the substitution of glutamic acid for valine in sickle-cell anemics. For ten points, identify this type of mutation that results from the addition, subtraction, or substitution of only one nucleotide base.
