why did RNA template from E.coli treated at 37 degrees celcius showed bands for groEL and rpOH in RT-PCR? They are supposed to be expressed only under stressed condition
How long did you grow your colonies and what was the final OD? Also, what growth media did you use? Bacteria get stressed with they run out of food, are surrounded by waste products, etc. It's pretty easy to stress bacteria if you grow them in non-ideal conditions.
