In order to understand how chromosomes move during anaphase of mitosis, researchers tagged ____ with a fluorescent label before photobleaching the cell and examining chromosomal movement under a microscope.
A) DNA
B) kinetochore microtubules
C) nonkinetochore microtubules
D) histones
E) motor proteins

Question

Quizplus · Accepted Answer

Kinetochore microtubules are directly involved in the movement of chromosomes during anaphase of mitosis. By tagging these structures with a fluorescent label, researchers can visualize and study how chromosomes are pulled apart to opposite poles of the cell.
