deamination of nucleic acids
- deamination of nucleic acids
-
The spontaneous loss of the amino groups of
cytosine (yielding uracil), methyl
cytosine (yielding thymine), or of
adenine (yielding hypoxanthine). It can be argued that the presence of
thymine in
DNA in place of the
uracil of
RNA stabilizes genetic information against this lesion, since repair enzymes would restore the GU base pair to GC.
