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。

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。

When regulatory molecules bind to this switch DNA, the contiguous gene is either expressed or prevented from being expressed.

当调控分子与这个开关dna结合时，相邻的基因便开始表达或终止表达。

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.

In order to operate, our cells constantly switch protein production on and off through specific gene functions.

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