11. Cell Division

Movement of the chromosomes during anaphase would be most affected by a drug that:

a) Prevents the formation of a cleavage furrow.

b) Prevents the formation of the nuclear envelope.

c) Prevents elongation of microtubules.

d) Prevents shortening of microtubules.

Cytokinesis usually follows mitosis. If a cell completed mitosis but not cytokinesis, the result would be:

a) A cell with a single large nucleus.

b) A cell with high concentrations of actin and myosin.

c) A cell with two abnormally small nuclei.

d) A cell with two completely identical nuclei.

e) A cell with two non-identical nuclei with half the amount of DNA.
