such as oxidation, reduction, and methylation. One of the most important properties of guanine is its ability to form three hydrogen bonds with cytosine. This strong base pairing is crucial for the ...

The DNA glycosylase MutY, which is a member of the Helix-hairpin-Helix (HhH) DNA glycosylase superfamily, excises adenine from mispairs with 8-oxoguanine and guanine. High-resolution crystal ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine ... via chemical bonds called phosphodiester ...

Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure ... the substitution of uracil with another nucleobase, such as cytosine (C) or guanine (G). These mutations ...
