'cytosine'是英语单词,中文翻译为“胞嘧啶”,是一种常见的有机化合物,是DNA和RNA的四种碱基之一。它的化学式为C4H5N3O,是一种咪唑类化合物,具有碱性。
以下是9个含有'cytosine'的例句:
1. Cytosine is one of the four bases that make up DNA.(胞嘧啶是构成DNA的四种碱基之一。)
2. The cytosine molecule contains a pyrimidine ring.(胞嘧啶分子含有嘧啶环。)
3. The nitrogenous base cytosine pairs with guanine in DNA.(DNA中,胞嘧啶与鸟嘌呤成对出现。)
4. Cytosine can be easily converted to uracil by spontaneous deamination.(胞嘧啶可通过自发的脱氨作用变成尿嘧啶。)
5. In RNA, cytosine pairs with guanine just like in DNA.(在RNA中,胞嘧啶像在DNA中一样与鸟嘌呤成对出现。)
6. The cytosine molecule contains a nitrogenous base and a sugar molecule.(胞嘧啶分子含有一个氮碱基和一个糖分子。)
7. Cytosine forms hydrogen bonds with guanine to stabilize the DNA double helix.(胞嘧啶与鸟嘌呤之间形成氢键来稳定DNA双螺旋结构。)
8. The cytosine content in a DNA sequence can affect its stability and function.(DNA序列中的胞嘧啶含量可以影响其稳定性和功能。)
9. The presence of cytosine methylation can regulate gene expression in cells.(胞嘧啶甲基化的存在可以调节细胞中的基因表达。)
