Taxol is an anticancer drug extracted from the Pacific yew tree. In animal cells, Taxol prevents microtubule depolymerization (breaking down). Thus, Taxol stops mitosis by interfering with which of the following structures or processes?
a) The mitotic spindle.
b) Cytokinesis.
c) DNA replication.
d) Chromosome condensation.

The circles labeled A to E each represent the chromosomes within a cell during a single phase of mitosis. Which image is showing one of the newly created nuclei at the end of telophase?

At which phase of the cell cycle do centrosomes begin to move apart in animal cells?

Scientists isolate cells in various phases of the cell cycle. They isolate a group of cells that have 1 1/2 times more DNA than G1 phase cells. What is the most likely part of the cell cycle from which these cells were isolated?

If there are 40 centromeres in a cell at anaphase of mitosis, how many chromosomes will be found in each daughter cell following cytokinesis?

a) 10.

b) 20.

c) 40.

d) 80.
