The aromatic rings in guanine's structure make it a relatively stable molecule, but it can still undergo various chemical reactions, such as oxidation, reduction, and methylation. One of the most ...

The majority of DNA methylation occurs at CpG sites, which are cytosines that precede a guanine nucleotide. Traditionally, methylation is examined at a specific CpG site independently of any ...

This modification is involved in epigenetic regulation, gene silencing, and DNA methylation patterns ... or from adenine to guanine (A → G) on the complementary strand. Transversion mutations: A ...
