Show transcribed image text Explain how the pausing of the ribosome in the presence or absence of tryptophan affects the formation of a rho-independent terminator stem loop? The sequential use of two sugars by a bacterium is known as diauxic growth. It is a common phenomenon among many bacterial species. When glucose is one of the two sugars, it is typical that the bacterium metabolizes glucose first, and then a second sugar after the glucose has been used up. Among E. coli and related species, diauxic growth is regulated by intracellular cAMP levels and the catabolite activator protein (CAP). Summarize the effects of glucose and lactose on the ability of the lac repressor and the cAMP-CAP complex to regulate the lac operon.
