DNA stands for deoxyribose nucleic acid.

DNA 代表脱氧核糖核酸。

RNA has a sugar called ribose, whereas DNA has a sugar called deoxyribose.

RNA 有一种叫做核酸糖的糖，而 DNA 有一种叫做脱氧核糖的糖。

Nucleotides of DNA are made out of a sugar deoxyribose, a phosphate, and one of the four nuclear bases: adenine, cytosine, guanine, and thymine or A, C, G, T for short.

DNA的核苷酸由脱氧核糖、磷酸以及四个核碱基之一组成，分别是腺嘌呤、胞嘧啶、鸟嘌呤与胸腺嘧啶，或简称A、C、G、T。
