What Do You Know About DNA And RNA Transcription? - Quiz

What do you know about DNA and RNA Transcription? Transcription takes place in two broad steps. The first stage involves the pre-messenger RNA being formed with the involvement of RNA polymerase enzymes. Do you remember the rest or do you need a refresher course? Take up this quiz and see just how much you got to understand from class. All the best!
