roots is 40% of maximal when there is no directional stimulus? Concentration in both c and d = ________ ACU 9b. What is the auxin concentration in region b given the conditions listed to the left of the figure? (60% elongation of either a or b, but you decide which) concentration in b =________ ACU 9c. What are the % of maximum elongation rates in E and F? E: _____ % maximum elongation F: _____ % maximum elongation 9d. What is the auxin concentration in region E given the conditions listed to the left of the figure? (60% elongation of either E or F, but you decide which) ________ ACU 9e. What would you predict the % of maximum elongation rate to be in regions a and b in a plant with a mutation that caused the plant to have a complete insensitivity to ethylene? a: _______ % maximum elongation b: _______ % maximum elongation

Bi212 Homework #4 Due Wednesday of week 9 @2pm page 6 Flower development 10. Scientists generated three constructs to create a remarkable looking plant with petals in the place of not only all other floral organs, but also in the place of all leaves! What three gene constructs did they use? Hint: They all had the same regulatory region. 11. In the spaces within the meristem diagram below indicate the location of the A,B, and C genes in a flower meristem in which the C gene is ectopically expressed throughout the flower at a concentration sufficient to suppress any genes it may regulate. In the space to the right of the meristem diagram name the organ identity you expect to find in this flower. 12. Sketch the basic mechanism of a fruit fly circadian clock.

    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.
