Question 10-12 10. During the mating process, yeast cells respond to pheromones secreted by other yeast...
You are interested in cell size regulation and discover that signaling through a GPCR is important in controlling cell size in rat white blood cells. The G protein downstream of this receptor activates adenylyl cyclase, which ultimately leads to the activation of PKA. You find that cells that lack the GPCR are 15% smaller than normal cells, whereas cells that express a mutant, constitutively activated version of PKA are 15% larger than normal cells. Furthermore, the normal blood cells become...
or each of the following sentences, select the best word or phrase from the list below to fill in the blanks ot all words or phrases will be used; each word or phrase should be used only once 38. (3) An extracellular signal molecule can act to change a cell's behavior by acting through cell that control intracellular signaling proteins. These intracellular proteins that bring surface signaling proteins ultimately change the activity of about cell responses. Intracellular signaling proteins can...

Question 36 1 pts 36. You have a population of mammalian cells growing in media containing enough growth factors. Which of the following graphs corresponds to these cells when their DNA content is analyzed 24 hours after they are induced to express high levels of a mutant form of Rb protein that cannot be phosphorylated?
