Praxis II: Biology Content Knowledge Exam Prep

Answer: B, cell cycle. The cell cycle controls the entire cycle of duplication and division of a cell’s contents.

Key Takeaway: The cell cycle is comprised of both mitosis and the events that proceed and follow it. Before mitosis can begin, a cell’s contents must be duplicated and enough nutrients stored so that mitosis can begin. This is known as interphase. The process of mitosis does not involve the actual formation of a new cell membrane to form two new cells. This takes place in a process called cytokinesis.
