s 9: JAK/Stat Pathway You are working with the JAK/Stat pathway in human cells. You decide to mutate the tyrosine in the receptor (that is known to be phosphorylated by JAK) to alanine (which can't be phosphorylated). Assume that all other functions of the receptor are active. Which of the following events or activities would still happen after making this mutation? Answer yes or no for each and briefly explain your reasoning. A. STATs will still be able to bind the receptor once the pathway is activated.- B. JAKs will still phosphorylate each other once the receptor dimerizes.- C. The signal will still cause the receptor to dimerize.- D. STATs will still be phosphorylated
