一未知结构的多糖，经完全甲基化和水解。
A polysaccharide of unknown structure was isolated, subjected to exhaustive methylation, and hydrolyzed.
由于不完全明了的原因，这种甲基化阻止这些基因的信息被表达，或者是转录至RNA和蛋白质——身体的基本组成要素。
For reasons that are not totally understood, this methylation prevents the gene's information from being expressed, or transcribed into RNA and proteins, the basic building blocks of the body.
因为我们每个细胞含有完全相同的DNA，我们机体有许多机制，如DNA甲基化，来控制一定类型细胞的基因表达，该过程称为基因组印迹。
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.
我们还不能完全理解剖宫产后dna -甲基化升高的重要性，但它一定会有很重要的临床作用。
"The full significance of higher DNA-methylation levels after C-section is not yet understood, but it may have important clinical implications" he says.
