Conclusions:It was first report that there were many new single nucleotide polymorphisms of lactase gene in this study including T-13908、C-13926、A-14010、G-13951、T-13952 allele,and T-13908 allele might be associated with lactase persistence in Hangzhou urban populations.
结论:首次发现乳糖酶基因在杭州市区人群中有多个新的单核苷酸多态性位点,包括T-13908、C-13926、A-14010、G-13951、T-13952等位基因。

将此基因与不同来源的乳糖酶基因序列进行比较发现,该基因与绝大多数乳糖酶基因同源性较低。
Comparing the gene cDNA and amino acid sequences with other lactase sequences from various sources, it showed a very low homology with most of other sequences.
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
