1·When a methyl group attaches to a specific spot on a gene - a process called DNA methylation.

甲基附加到基因上某个特殊点的过程，称为DNA甲基化。

2·The team looked at methylation, in which a methyl group is placed onto cytosine in DNA sequences.

工作小组关注甲基化作用，是指一个甲基群被放在DNA序列的胞嘧啶上面。

3·The methyl group (CH3) attached to the methionine sulfur atom in SAM is chemically reactive.

甲基基团（CH3）附着在SAM中蛋氨酸硫原子具有化学反应性。

4·A methyl group is a basic unit in organic chemistry: one carbon atom attached to three hydrogen atoms.

甲基是有机化学的基本单位：一个碳原子连接三个氢原子。

5·Trigonelline is unstable above 160 degrees F; the methyl group detaches, unleashing the niacin-vitamin b3-into your cup.

胡芦巴碱华氏160度以上时化学性质不稳定，甲基脱落，释放出烟碱酸，也就是维生素b3。

6·Conclusion Introducing the methyl group or a low alkyl group resulting in the high selectivity and increase of its activity.

结论甲基或低级烷基的引入导致了高选择性，使其活性增大。

7·Much is known about the fifth base, 5-methylcytosine, which arises when a chemical tag or methyl group is tacked onto a cytosine.

此前，科学家们已对第5种碱基有所了解——当一个化学标签或甲基被固定到一个胞嘧啶上时，第5种碱基就会出现。

8·In healthy cells a compound called a methyl group is tagged to DNA where it ACTS as a red light, preventing certain genes from producing proteins.

在正常细胞中，甲基作为DNA标记的一个“红灯”，阻止某些基因合成蛋白质。

9·Substitution of methyl group at 1,2 and 3 position on 1-methylindole, 2-methylindole and 3-methylindole inhibits initial microbial attack significantly.

同时，1、2或3位上的甲基替代使1 甲基吲哚，2 甲基吲哚和3 甲基吲哚的降解受到严重抑制。

10·Thymine: Organic compound of the pyrimidine family, often called a Base, consisting of a ring containing Both nitrogen and carbon atoms, and a methyl group.
