Balbiani rings are sites of :
Nucleotide synthesis
Polysaccharide synthesis
RNA and protein synthesis
Lipid synthesis
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.
