Morphology

nucleotide = nucleoside (opaque) = nucleo + tide

The word is built from specialized biochemical combining forms ('nucleo-' and '-tide') and the relation to everyday English words is not inferable by an average B1 learner.

Etymology

The word nucleotide comes from nucle- meaning 'kernel' or 'center', the same root you see in nucleus, and from -tide, a part used to name small units like nucleoside. So a nucleotide is a small 'building block' that makes up DNA and RNA.
