To Study Chromosome Movement During Anaphase in Mammals, You Have

question 12

Short Answer

To study chromosome movement during anaphase in mammals, you have injected fluorescently labeled tubulin subunits into cells such that microtubules can be seen under a fluorescence microscope. You then use a relatively strong laser beam to bleach the fluorescent dyes in a limited area of a metaphase cell, as indicated in the schematic diagram below, and follow the progression of mitosis under the microscope by time-lapse imaging. You then use the images to measure the change in distance between various components, and plot the results in the graph below. Answer the following question(s) based on these results.

-Based on the results from the experiment, which is dominant in this cell: anaphase A or anaphase B? Write down A or B as your answer.
