We're looking at gene promoters and what would be their master switch.

我们正在研究基因启动器以及什么会是它们的主开关。

They then found that the switch of a single DNA unit in the gene determines whether a person has wet or dry earwax.

他们发现基因中dna单链上的基因单元具有像开关一样的物质，该物质决定了人们的耳垢类型。

So, very crudely, the thing on the wall is the switch DNA, your finger is the regulator, and gene expression is the light turning on or turning off.

因此，大体上可以这么形容，在墙上的东西就是开关DNA，手指是调控器，基因表达就是打开灯或关闭灯。

For example, Zeneca has managed to switch the bt gene, which gives maize plants resistance to nasty insects, on and off using another chemical trigger.

Dr Audero's experiment did not manipulate the receptor gene directly but, rather, manipulated its activity using the switch.
