Answer #1

A. Gene regulation is gene expression i.e., genes being turned on and produce a product. So a gene regu,ation/ expression can be at several steps.

Pre-transcriptional control , during the sysnthesis of mRNA

poso-transcriptional control , during processing of mRNA or during translation process

post translational control, during the process of maturation of the protein formed to becomes functional.

The cell has a wide range of mechanism to increase or decrese the production of specific gene products. For ex. The hormone production decreases or increases depending upon the feed back mechanism.

Any step of the gene expression can be modulated by the cell from transcription, RNA processing and translation.

B. The cells use different controls and cannot use one control because one gene regulator controls another and so on which takes place as a sequence in a gene regulatory network.
