It is important in epigenetics, because the hydroxymethyl group on the cytosine can possibly switch a gene on and off. en.wikipedia.org

It most commonly pairs with thymine as an adenine-analogue, but can also pair with cytosine as a guanine-analogue;. en.wikipedia.org

Some examples include hypoxanthine, dihydrouracil, methylated forms of uracil, cytosine, and guanine, as well as modified nucleoside pseudouridine. en.wikipedia.org

Adenine and guanine are purines, while thymine, cytosine and uracil are pyrimidines. en.wikipedia.org

During normal cellular activities, guanine sometimes becomes altered by oxygen, which causes it to pair with adenine instead of cytosine. en.wikipedia.org

The most common nitrogenous bases are adenine, cytosine, guanine, thymine, and uracil. en.wikipedia.org

Certain nucleic acid combinations will decrease unwinding rates (i.e. guanine and cytosine), while various destabilizing forces can increase the unwinding rate. en.wikipedia.org

Most histone methylation occurs in the promotor region, and is similar to cytosine methylation in process and function. en.wikipedia.org

The most common mutation is the deamination of cytosine to uracil. en.wikipedia.org

This pairing always occurs in specific combinations, with cytosine and guanine always forming a pair and thymine and adenine always forming a pair. en.wikipedia.org
