1·Other epigenetic processes appear to occur randomly, while others are normal, such as those that guide embryonic cells as they become heart, brain, or liver cells, for example.
其他的表观遗传过程似乎是随机发生的，而其他过程则是正常的，比如那些引导胚胎细胞成为心脏、大脑或肝细胞的过程。
2·Epigenetic processes are chemical reactions tied to neither nature nor nurture but representing what researchers have called a "third component".
表观遗传过程是一种化学反应，与天生和后天培养都没有关系，但它代表了研究人员所说的“第三种成分”。
3·Environmentally triggered alterations in genes - known as epigenetic changes - can affect when a gene is activated, how robustly it is turned on and how it interacts with neighboring genes.
环境所引发的基因变异被称为“表观遗传变化”，它可能会影响基因被激活的时间、被激活的程度以及它如何与邻近基因相互配合。
4·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。
5·When animals are cloned, epigenetic changes can occur.
克隆动物后，表观遗传的变化就会发生。
1·This latest study focuses on what are called the "epigenetic" mechanisms which can affect whether a gene is expressed or not.
最新研究集中在“后生”机制，该机制影响基因。
2·Cancers arise through the accumulation of genetic mutations and epigenetic modifications.
癌症是通过基因突变和后生修改的积累产生的。
3·Teratocarcinomas can arise through purely epigenetic changes and represent an extreme case in which the transformed phenotype can be abrogated under appropriate conditions.
畸胎瘤可能仅仅因为后生改变而出现，这代表一个极端的例子，其转化表型可以在适当条件下被废除。
4·Furthermore, the very same class of mutator enzymes plays an underappreciated role in non-lymphoid cancers, in antiviral responses and in epigenetic reprogramming.
此外，同一类的增变基因酶起着低估的作用，在非淋巴肿瘤，抗病毒反应，并在后生重新编程。
5·The paper introduces polluted irritation of industrial and urban wastewater and its effect of minimization, resource, then the epigenetic pollution control and prevention countermeasures are proposed.
该文介绍了工业和城市废水污灌，使其减量化、资源化的作用与效果，论述了后生污染控制及防治对策。
