DNA methylation is an important regulation of gene express in eukaryotic cells, and is one of the most common modifications of the transcription level.

DNA甲基化是基因表达的重要调控方式，是真核细胞中最常见的转录水平的修饰方式之一。

There are many biological response paths in a cell, such as material metabolism paths, gene express paths, DNA duplication paths, signal transduction paths and so on.

细胞中有许多生物反应通路，比如物质代谢通路、基因表达通路、DNA复制通路、信号转导通路等等，其中最复杂的就是信号转导通路。

To estimate effect of different zinc sources on early performance and correlative gene express of piglet, forty-five 28-day-old weaned piglets were randomly divided into three groups of 15 each.

利用不同的锌源饲喂早期断奶仔猪，研究其对仔猪早期生长的影响，并从激素水平及基因表达上探讨其可能的作用机制。

Now in this case the host - you want the host not only to replicate all the DNA, you want it also to express the gene.

而这种情况下宿主--,你不只希望宿主复制基因,同时也想使之表达基因

So it's going to express this gene, but you've put a foreign gene in the place of the natural gene, and so the foreign gene gets expressed instead.

所以它就会表达这段基因,但是你已经用一段,异源基因替代了原有基因,因此这段外来基因就被表达了

The second issue is that the gene vector, in this case the plasmid, has to be compatible with the cells that you're trying to express the gene in.

接下来的问题是如何选择合适的基因载体,在这里用到的,质粒,必须与要用来表达基因的,受体细胞匹配
