During which phase of the cell cycle does most cell growth occur?

• cytokinesis
• interphase
• metaphase
• prophase

Why must DNA replication have to occur before a cell can divide by mitosis?

• to maintain the same number of chromosomes in the daughter cells as in the parent cell
• to cause one of the cells produced to have double the number of chromosomes as the parent cell
• to allow crossing over to occur in each of the cells produced
• to cause all of the cells produced to have half the number of chromosomes as the parent cell

These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.
• Mutations in the cells’ nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.
• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.

Why is it important for cells of multicellular organisms to undergo mitosis?

• Mitosis allows for reproduction with male and female gametes.
• Mitosis increases variation within an organism.
• Mitosis produces cells that are different from the original dividing cell.
• Mitosis produces cells that are identical to the original dividing cell.

Examine the following picture of a cell. Which of the following descriptions best describes what is taking place here?

• The cell is undergoing DNA replication.
• The nuclear membrane has disintegrated and the spindle fibers are attaching to the sister chromatids.
• The chromosomes are lined up on the metaphase plate.
• The sister chromatids are being pulled by the spindle fibers toward opposite poles of the cell.
