A purine base found in DNA and RNA; pairs with cytosine. DNA和RNA中的嘌呤碱,与胞核嘧啶成对。
Cytosine(C) methylation silences transposable elements in plants, vertebrates, and fungi but also regulates gene expression. 胞嘧啶(C)的甲基化能够沉默植物、脊椎动物和真菌的转座元件,同时也能调控基因的表达。
There are just four kinds : adenine, thymine, guanine and cytosine. 只有4种:腺嘌呤、胸腺嘧啶、鸟嘌呤和胞核嘧啶。
The other two, thymine and cytosine, are single ring structures called pyrimidines. 另两个为胸腺嘧啶和胞嘧啶(C),即称为嘧啶的单环结构。
