• 12
• 23

• 92

What is a series of events a cell goes through as they grow and divide?

• Cell Division
• Cell Cycle
• Cytokinesis
• Mitosis

Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase. 

• prophase, metaphase, telophase, anaphase
• prophase, anaphase, metaphase, telophase
• prophase, metaphase, anaphase, telophase
• prophase, telophase, metaphase, anaphase

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.
