Summary of gene expression starting with DNA anding with proteins.

Normally, transcription begins when an RNA polymerase binds to a so-called promoter sequence on the DNA molecule. ... Some regulatory proteins affect the transcription of multiple genes. This occurs because multiple copies of the regulatory protein binding sites exist within the genome of a cell.
