DNA Methylation

基本解释

The process, known as DNA methylation, is one mechanism of epigenetic change, heritable change that does not alter the sequence of DNA itself.
该过程被成为DNA甲基化，是表观遗传变化的一种，属于不会改变DNA序列的可遗传变化。
An analysis of a person's DNA methylation finds that the number of methyl groups attached to the DNA correlates with the person's age--making saliva analysis a possible CSI tool.
对人体DNA甲基化水平进行检测发现，结合在DNA上的甲基团数量与年龄有关，因此，唾沫分析技术有望成为犯罪现场取证工具。
Because we have identical DNA in each of our cells, our bodies have mechanisms, such as DNA methylation, to control which genes are expressed in certain cell types—a process called genomic imprinting.
因为我们的每一个细胞中都有同一DNA，所以我们的身体具备机制，譬如DNA甲基化，以控制在特定类型细胞中表达哪些基因——这个过程被称为基因组印记。

DNA methylation shows chemical changes in a person's deoxyribonucleic acid,or DNA.
The study found that sixteen babies born by C-section had higher DNA-methylation rates immediately after they were born than the other babies.
They examined DNA-methylation in the white blood cells.
