nucleosides

/ˈnjuːkliəˌsaɪdz/ /ˈnukliəˌsaɪdz/

Meanings

noun

An organic molecule in which a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine, is covalently attached to a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA). When the phosphate group is covalently attached to the pentose sugar, it forms a nucleotide.

Examples :

"Example Sentence: "Cells build DNA and RNA using smaller building blocks called nucleosides and nucleotides." "
