研究者们相信：在异源环境中，多种多样的基因型是一项有用的生存工具。

The researchers believe that a more diverse set of genes is a useful survival tool in a heterogeneous environment.

目的：评价异源双链分析（HET）和单链构象多态性分析（SSCP）在基因突变检测中的作用。

Objective:To assess the roles of single stranded conformation polymorphism(SSCP)and heteroduplex polymorphism(HET)in screening gene mutation.

It's a mechanism that they have evolved in order to prevent foreign genes from entering a cell and being expressed.

它们进化出这种机制来,防止异源基因进入细胞并表达

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

Taking foreign genes, genes that aren't naturally expressed or might not even exist inside a cell and putting them there and putting them there in a way where they work, and by work meaning the gene gets expressed or translated into a protein.

将异源基因,即那些在细胞中原本不表达或者,根本不存在的基因转入细胞并让它们工作,工作就是指让基因持续表达并合成蛋白质
