此前研究人员发现了其它高度保守的开关，当他们从小鼠基因组中剔除这类开关时就能帮助减少焦虑症、食欲和对酒精的摄入，同时研究人员还提供了模板帮助深入揭示增强子在复杂疾病相关行为中的功能。文章第一作者Andrew ...

But another region of the gene, called "regulatory DNA," determines whether and when the gene will be expressed, or turned on, in a particular kind of cell. If you're a brain cell, for instance ...

In addition, regulatory sites on prokaryotic DNA are typically located close to transcription promoter sites — and this plays an important part in gene expression. For an example of how this ...

Genes also contain regulatory sequences, such as promoters and enhancers ... This process is carried out by the enzyme RNA polymerase, which binds to the promoter region of the gene and synthesizes ...
