Select the appropriate option with respect to gene regulation
I. The activity of RNA polymerase in transcription at a given promoter is in turn regulated by interaction with accessory proteins
II. The regulatory proteins in an operon can act both positively (repressors) and negatively (activators)
III. The operator region is adjacent to the promoter elements in most operons
IV. Lac operator is present only in the lac operon and it interacts specifically with lac repressor only
