What Do You Know About DNA And RNA Transcription?

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!
