WebWhat happens during cytosine deamination and how is it repaired? Deamination converts a cytosine base into a uracil. This results in a double helix in which a G in one strand is paired with a U in the other. The U was formerly a C, but was converted to U via deamination. The uracil is detected and removed, leaving a base-less nucleotide. Web30 dec. 2024 · Another deamination, of the modified base methylcytosine, can also lead to a mutation upon replication.
