甲基化作用代表性的抑制了基因，因此他们没有被表达。
Methylation typically silences genes so that they are not expressed.
甲基化作用关闭基因。
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。

漆酶的去甲基化作用可以使木质素降解，也能够参与自然界中花色的形成。
The demethylation of laccase is applied to lignin degradation and formation of color within natural flowers.
甲基化作用是对DNA的后天修改，并改变基因活动，通常是在基因组内减少这个活动。
Methylation is an epigenetic modification to one's DNA that changes a gene's activity, generally reducing that activity within the genome.
这个甲基化作用同基因沉默有关，因为它会导致DNA的双螺旋折叠得更加紧密。
This methylation is associated with gene silencing, as it causes the DNA's double helix to fold even tighter upon itself.
