Question

8. In the following graph that shows changes in the lengths of two microtubules over time, which time point corresponds to a catastrophe for both microtubules? Which trace corresponds dynamic instability? to a microtubule with greater long short o ti Time A. ti; microtubule (a). B. ti; microtubule (b). C. t2: microtubule (a). D. D. t; microtubule (b). would increase/over-activate the function of the 9. A mutation that inactivated/distorted phototransduction pathway A. PDE6B B. Transducin. C. Rhodopsin. D. CNGA/B1. E. None of the above 10. When would you expect dynein to become most active? A. Prophase. B. Prometaphase. C. Anaphase A. D. Anaphase B. E. Telophase.

Explanation / Answer

Ans 8 : D) t2 ; microtubule (b)

The t2 time point in the graph shows the catastrophe for both the microtubules. The dynamic instability of the microtubule (b) is greater as it shows maximum fluctuations in the graph , as visible in the picture.
