How do the genes in e. coli save energy
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. WebWhile most prokaryotes, like E. coli, contain a single circular DNA molecule that makes up their entire genome, recent studies have indicated that some prokaryotes contain as many as four...
