DNA Methylation

基本解釋

The process, known as DNA methylation, is one mechanism of epigenetic change, heritable change that does not alter the sequence of DNA itself.
該過(guò)程被成為DNA甲基化，是表觀遺傳變化的一種，屬于不會(huì)改變DNA序列的可遺傳變化。
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.
對(duì)人體DNA甲基化水平進(jìn)行檢測(cè)發(fā)現(xiàn)，結(jié)合在DNA上的甲基團(tuán)數(shù)量與年齡有關(guān)，因此，唾沫分析技術(shù)有望成為犯罪現(xiàn)場(chǎng)取證工具。
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?yàn)槲覀兊拿恳粋€(gè)細(xì)胞中都有同一DNA，所以我們的身體具備機(jī)制，譬如DNA甲基化，以控制在特定類型細(xì)胞中表達(dá)哪些基因——這個(gè)過(guò)程被稱為基因組印記。

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.
