Purine bases end with which suffix?

Explanation:
When naming nucleosides, the suffix tells you which type of base the sugar is attached to. Purine bases, like adenine and guanine, form nucleosides that end with -osine, giving adenosine and guanosine. This pattern helps distinguish them from pyrimidine bases (cytosine, thymine, uracil), which form nucleosides that end with -idine (cytidine, thymidine, uridine). So the suffix -osine is the one used for purine-derived nucleosides, while -idine is used for pyrimidine-derived nucleosides.
