A base found in DNA and RNA and derived from pyrimidine; pairs with guanine. DNA和RNA中的碱,由嘧啶衍生而来,与鸟嘌呤(G)成对。
There are just four kinds : adenine, thymine, guanine and cytosine. 只有4种:腺嘌呤、胸腺嘧啶、鸟嘌呤(G)和胞核嘧啶。
Researchers at Purdue University used synthetic forms of guanine and cytosine. 美国普渡大学的研究人员使用的是合成的鸟嘌呤(G)与胞嘧啶。
It stores information as a sequence of chemical building blocks ( nucleotides ) we call A, C, T, and G ( for adenine, cytosine, thymine, and guanine in DNA, and uracil replacing thymine in RNA ). 它将信息存储为化学基本成分序列(核苷),我们将其称作A、C、T和G(表示DNA中的腺嘌呤、胞嘧啶、胸腺嘧啶和鸟嘌呤(G),以及RNA中的尿嘧啶代替胸腺嘧啶)。
DNA consists of a chain made from four types of nucleotide subunits : adenine, cytosine, guanine, and thymine. 的DNA链组成一个由4种核苷酸亚基:腺嘌呤,胞嘧啶,鸟嘌呤(G)和胸腺嘧啶。
