I would like to modify the following sentence to change the location of the promoter to the opposite side.

"TK promoter in front of the ICP27 gene in both vectors"

Would it be as following?? "TK promoter at back of the ICP27 gene in both vectors"

    What exactly does "in front of" imply here? Why is behind not the natural choice? Can you expand?

  • You nee to give the full sentence of the original. Is a 'promoter' another gene in the sequence? Or is it a process that applies to the gene? Or to the vector? We're not geneticists here. In fact, that may give you a clue that it might be better to ask this on Biology.SE.
