You are studying a microorganism in which a “male” turns pink in the presence of a “female.” The male becomes pink because a protein X secreted by the female binds to and activates a protein Y on the male that causes the color change. You have isolated a strain of the microorganism that produces a mutant form of protein X that works normally at temperatures lower than 37°C, but at higher temperatures it cannot induce the pink color. Could any of the following changes in mutant protein X explain your results? If so, state the letter of which ones, and explain why. a. It makes an extra hydrogen bond to protein Y. b. It makes fewer hydrogen bonds to protein Y. c. It makes a covalent bond to protein Y. d. It starts becoming unfolded at temperatures lower than 37°C. e. It starts becoming unfolded at temperatures higher than 37°C. f. It is unable to bind to protein Y at any temperature.
