In 1931, a chemist named Arthur Fox was pouring some powdered PTC (phenylthiocarbamide) into a bottle when some of the powder accidentally blew into the air. A colleague standing nearby complained that the dust tasted bitter. Fox tasted nothing at all. Curious how they could be tasting the chemical differently, they tasted it again. The results were the same. Fox had his friends and family try the chemical then describe how it tasted. Some people tasted nothing. Some found it intensely bitter, and still others thought it tasted only slightly bitter (from The University of Utah Genetic Science Learning Center, 2013). It is estimated that 70% of the population can taste PTC and 30% cannot. We also know that the ability to taste PTC is passed from parent to child.
Which of the following molecules is responsible for the fact that parents who can taste PTC will most often have children who can taste PTC?

After the close of the [Civil War], while working in the coal-mines of West Virginia for the support of my mother, I heard in some accidental way of the Hampton Institute. When I learned that it was an institution where a black boy could study, could have a chance to work for his board, and at the same time be taught how to work and to realize the dignity of labor, I resolved to go there. Bidding my mother good-by, I started out one morning to find my way to Hampton, though I was almost penniless and had no definite idea where Hampton was. By walking, begging rides, and paying for a portion of the journey on the steam-cars, I finally succeeded in reaching the city of Richmond, Virginia. I was without money or friends. I slept under a sidewalk, and by working on a vessel next day I earned money to continue my way to the institute, where I arrived with a surplus of fifty cents. At Hampton I found the opportunity—in the way of buildings, teachers, and industries provided by the generous—to get training in the class-room and by practical touch with industrial life, to learn thrift, economy, and push. I was surrounded by an atmosphere of business . . . and a spirit of self-help that seemed to have awakened every faculty in me.

(from "The Awakening of the Negro" by Booker T. Washington)
