Genetics (PCB 3063 Section 4462)-Quiz Answers Import things to note: The drawn out structures are intermediates. They are not colored compounds. The bold italics letter and number combinations are the genes that encode the enzymes involved in the pathway (ex TT4 ) . The colored compounds are the ones that are written in standard, bold, non-italic font (ex Tannins). Also, note that there are branches in the pathways. There are actually seven different pathways that lead to end colored products. In the case of Tannins, there are two different pathways that lead to them. Be sure to be able to follow each of these pathways. Questions: 1. If you have a mutation in TT4, which colored compounds would accumulate? Follow the pathway from the top until you reach TT4. If that gene is mutated, then the pathway is interrupted at that point. That means that everything before it will accumulate and everything after it will not (unless there is an alternate gene that will compensate, or a “detour”).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
