One of them has the right sequence of codons to specify the amino acid sequence of the protein, and the other one has a complimentary sequence.

该段带有正确的密码子序列,能够指导氨基酸序列合成蛋白质,另一段则是它的互补序列

The promoter in this case is called the lac promoter and normally in micro-organisms that lac promoter is used to produce a gene called lacZ which makes a protein called beta-galactosidase.

在这个例子中的启动子称作lac启动子,通常在微生物中,lac启动子是用来生成,一段叫lacZ的基因,这段基因,能制造一种蛋白叫β-半乳糖苷酶

In this case the promoter, which is a sequence of DNA that is positioned right in front of the gene of interest, the promoter is the betagalactoglobulin promoter in this case, and betagalactoglobulin is a milk protein.

这里涉及到的启动子,也是一段DNA序列,它必须刚好位于目的基因序列前端,我们用到的是β-乳球蛋白启动子,β-乳球蛋白是乳汁中的一种蛋白
