Question

broadly explain, transcriptional regulation of mammalian gene expression.​

Answer 1

Answer:

Regulation of gene transcription is the primary means by which gene expression is controlled to produce different proteins in different cell types or in response to different stimuli. ... Many transcription factors contain specific activation domains which allow them to activate transcription

Explanation:

The maltose operon is an example of a positive control of transcription. ... This prevents the activator protein from binding to the activator binding site on the gene, which in turn prevents RNA polymerase from binding to the maltose promoter
