Hello Saeed.

Environmental ques such as pH would cause tremendous changes in gene expressions as cell survival responses.

Have a look at the followings;

Kunal Pal, you are simply copying what Sang Ho Lee already had written. You could at least have corrected his spelling mistake, but you even copied that. Please stop.

Thanks all,

Your answers have been very helpful.

Let's say that I am interested in "promoter" of a those gene(s).

In fact, I need to find a promoter that can stop transcription at low pH, but start transcription at high pH. I am looking for a specific gene name in human cell with mentioned promoter.
