Mitosis

What is the end result of the cell cycle and mitosis?

• Formation of three identical daughter cells
• Formation of one identical daughter cell
• Formation of two non-identical daughter cells
• Formation of two identical daughter cells

Why does the DNA have to be copied before mitosis?

• To prevent the DNA from being damaged during mitosis.
• To increase the size of the DNA molecules.
• To allow for genetic variation in the new cells formed during mitosis.
• To ensure that each new cell formed during mitosis has a complete set of genetic information.

Which of the follow are the events of the cell cycle in the correct order?

• Prophase, metaphase, anaphase, telophase, cytokinesis, interphase
• Metaphase, anaphase, telophase, cytokinesis, interphase, prophase
• Cytokinesis, interphase, prophase, metaphase, anaphase, telophase
• Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
