WebThe cell detects the growth factor through physical binding of the growth factor to a receptor protein on the cell surface. Binding of the growth factor causes the receptor to change shape, triggering a series of chemical events in the cell that activate proteins called transcription factors. WebTo begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. Each gene (or, in …
