Movement of the Chromosomes During Anaphase Would Be Most Affected

Question

Movement of the chromosomes during anaphase would be most affected by a drug that
A)reduces cyclin concentrations.
B)increases cyclin concentrations.
C)prevents elongation of microtubules.
D)prevents shortening of microtubules.
E)prevents attachment of the microtubules to the kinetochore.

Accepted Answer

During anaphase, chromosomes are pulled apart to opposite poles of the cell. This movement is facilitated by the shortening of microtubules. A drug that prevents the shortening of microtubules would directly interfere with this process, thus most affecting the movement of chromosomes during anaphase.
