The difference between Nucleobase and Nucleotide

When used as nouns, nucleobase means the base of a nucleic acid, such as thymine, uracil, adenine, cytosine and guanine, whereas nucleotide means the monomer constituting dna or rna biopolymer molecules. each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine.
