Gene expression in eukaryotes is regulated primarily at the level of transcription.

在真核生物中基因表达的调节主要是在转录水平。

Gene expression is regulated by the complex interaction of many cis-acting elements and trans-acting factors.

基因表达是由众多顺式作用元件和反式作用因子相互作用调控的。

Promoters are important elements that regulated gene expression, activity of promoters indirectly reflect gene expression that they control.

启动子是基因表达调控的重要元件，启动子的活性间接反映了它所控制的基因的表达。

In order to ensure that this gene expression is properly regulated, the researchers also introduced a different molecule into the yeast.
