Contiguous to each gene is DNA that doesn't code for protein; instead, it functions as the gene's on-off switch.

每个相邻基因之间是不能编码蛋白质的dna；相反，它起着基因启动-关闭开关的功能。

Dr Chalfie realised that if the GFP gene could be spliced into a chromosome next to the gene for a protein of interest, it would be controlled by the same genetic switch as that protein.
