Quizplus · Accepted Answer

Purine type of nitrogenous bases includes adenine (A) and guanine (G), which are larger molecules consisting of a two-ring structure. Among the options given, only option E corresponds to a purine base, as the numbers do not directly indicate known nitrogenous bases but assuming standard options, adenine and guanine are the correct purines.
