Root Explanation

Nucleoside → It is formed from "nucleus" (from Latin *nucleus*, meaning kernel or core) and "-side" (from Greek *sida*, meaning a compound or substance). The word "nucleoside" refers to a compound that is a core part of nucleic acids, consisting of a sugar and a nitrogenous base.

Memory Tip
