During which phase of the cell cycle do chromosomes duplicate?

• G1

• S

• G2

• Mitosis

What is the difference between a cell in the G1 phase and a cell in the G2 phase of the cell cycle?

• A cell in the G2 phase will be smaller than a cell in the G1 phase

• A cell in the G2 phase of the cell cycle will have more mitochondria than a cell in the G1 phase

• A cell in the G1 phase of the cell cycle will have more DNA in its chromosomes than a cell in the G2 phase

• DNA replication occurs in the G1 phase but not in the G2 phase

What would show that a person has metastatic cancer?

• Alveolus cell forming a tumor in the lungs

• Cancer cells producing the skin pigment melanin in the liver

• A tumor in the prostate gland increasing levels of prostate-specific antigen

• Cancerous lymphocytes in the blood plasma

Students examined micrographs and counted cells in different stages of mitosis as well as those cells with no visible chromosomes. The table shows their results. What is the mitotic index?

The diagram illustrates two cells at the point of cytokinesis. In what way is cytokinesis different in plants and animals?

• In animals the cytoplasm is divided by narrowing forming a cleavage furrow, while in plants a cell plate forms a new cell wall.

• In plants the cytoplasm is divided by narrowing forming a cleavage furrow, while in animals a cell plate forms a new cell wall.

• In plants cytokinesis divides the cytoplasm during anaphase while in animals it divides after anaphase.

• In animals the cytoplasm is divided equally in cytokinesis, but in plants it divides unequally.
