amplification in no RT control

... exposure to antimicrobials. RNA has been isolated by trizol method and subsequently 'cleaned' on column and finally been DNase treated prior to reverse transcription. I am getting amplification in all of my no RT controls (4 treatments and an untreated), although this is occurring ~20 cycles ...

Re: Why is ATP rather than GTP, CTP or TTP the energy currency?
