Meanings

noun

核苷，苷

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 :

"Sentence: "The building block of DNA, the nucleoside adenosine, consists of the base adenine attached to a sugar molecule." "

构成DNA的基本单元，核苷腺苷，是由碱基腺嘌呤连接到一个糖分子构成的。
