According role of regulatory proteins, RNA polymerase and one or more promoter elements, mostly three levels of transcription are there, choose correct one

#Part-A Aptitude & General Biotechnology
  1. RNA polymerase occasionally binds the promoter spontaneously – No transcription

  2. Binding of the repressor to the operator- Basal level

  3. If both the repressor and activator are present and functional, the action of the repressor typically overcomes that of the activator - Activated level

  4. A & B both are correct
