Structurally, a gene is formed by three regions: a regulatory region called the promoter juxtaposed to the coding region containing the protein sequence, and a “3’ tail” sequence.

从结构上来讲，基因包含三个区域：称为启动子的调节区域；与其并列的编码蛋白质的密码子区域；以及3'端尾部序列。

Studying the gene sequence of treponema and twocomponent regulatory systems may provide the theoretical basis for explaining the above phenomena.

研究密螺旋体的基因序列和双组分调控系统可能为解释上述现象提供了理论依据。

Known as a regulatory sequence, the difference is on dog chromosome 15 next to a previously known gene named IGF1, for insulin-like growth factor 1.

已经知道该片段是一段调节序列，不同之处在于狗的第15染色体，与已知的名叫IGF1的基因相邻。IGF1指的是胰岛素状生长因子1。

It is a fast-growing North Atlantic salmon that contains a new Chinook salmon growth hormone gene and a DNA regulatory sequence that keeps the gene turned on all year instead of only during the warmer months, as in nature.
