As we learnt in

Activators and repressors -

In a transcription unit, the activity of RNA polymerase at a given promoter is in turn regulated by interaction with accessory proteins which affect its ability to recog

- wherein

These regulatory proteins can both positively (activators) and negatively (repressors).

 

 A Balbiani ring is a large chromosome puff. Balbiani rings are diffused uncoiled regions of the polytene chromosome that are sites of RNA transcription and protein synthesis.
