WebDiscuss the role of transcription factors in gene regulation. Like prokaryotic cells, the transcription of genes in eukaryotes requires the action of an RNA polymerase to bind to a DNA sequence upstream of a gene in order to initiate transcription. However, unlike prokaryotic cells, the eukaryotic RNA polymerase requires other proteins, or ... WebThe main control point for gene expression is usually at the start of transcription. That is, controlling the signal that tells the cell to produce this mRNA and make this protein. Transcript processing provides an …
