Mutations can occur when adenine is altered or mismatched with other bases. For example, the deamination of adenine can lead to the formation of hypoxanthine, which can pair with cytosine instead of ...

Inosine can pair with adenine, cytosine, or uracil ... to inosine (I) by hydrolytic deamination. Since inosine is interpreted as guanosine (G) by the cellular machinery, A-to-I editing can alter ...
