5.(1 pt) The figure below diagrams the yeast pathways that respond to mating pheromone andosmoloarity. Which ONE of the followingMOSTaccurately predicts the effect(s) that amutation that eliminates scaffolding protein 2 would have on activation of the kinase D?a.Increased sensitivity to high osmolarityb.Increased sensitivity to the mating factorc.Decreased sensitivity to osmolarityd.Decreased sensitivity to the mating factore. A + Bf.A + Dg. B+ Ch. C+D
6.(1 pt) Nitroglycerine is a drug that is converted to NO in the body and is used as a treatmentfor angina, which is pain resulting from inadequate blood flow to the heart (Nitroglycerine isalso an explosive, but that would be an “off label” use of the drug). Remarkably, within fiveminutes of placing a Nitroglycerine tablet under the tongue of a patient, the smooth musclesin the heart vasculature relax, which increases blood flow and relieves angina pain. Basedon these observations, which ONE of the following is the most likely mechanism by whichNO relieves angina pain?
BioSci219, 2019 Prof. BeitelQuiz 6(18.5 points, ~30 minutes)2-20-20197.(1 pt) A synthetic biologist wants to build a bistable genetic toggle switch.The switch shouldhave the behavior shown in the figure below. When a pulse of Isopropyl β-D-1-thiogalactopyranoside (IPTG) is applied, a stable state where gene X has high expressionand gene Y has low expression should be achieved. Both X and Y have a strong expressionif not regulated by other factors. When a pulse of anhydrotetracycline (aTc) is applied, astable state where gene X has low expression and gene Y has high expression should beachieved.Which ONE of the following diagrams represents the design that wouldBESTcreate thebehavior desired by the synthetic biologist?8.(1 pt) Which ONE of the following isNOTan example of positive feedback?
