Cell Cycle and Mitosis

What are the three main stages of the cell cycle?

• Prophase, Anaphase, Telophase

• Interphase, Mitosis, Cytokinesis

• G1 phase, S phase, G2 phase

• Metaphase, Anaphase, Telophase

During which stage of the cell cycle does DNA replication occur?

• Cytokinesis

• Interphase

• Mitosis

• Prophase

What is the purpose of the interphase in the cell cycle?

• The purpose of the interphase is to allow the cell to grow and perform its normal functions before proceeding to the next phase of the cell cycle.

• The purpose of the interphase is to store excess nutrients

• The purpose of the interphase is to repair damaged Daughter cells

• The purpose of the interphase is for cells to divide

What is the main difference between mitosis and meiosis?

• The main difference is the number and genetic variation of daughter cells produced.

• The main difference is the color of the daughter cells produced.

• The main difference is the temperature at which the process occurs.

• The main difference is the type of cells that undergo the process.

List the four stages of mitosis in order.

• prophase, metaphase, anaphase, telophase

• prophase, anaphase, metaphase, telophase

• interphase, metaphase, anaphase, telophase

• prophase, metaphase, telophase, anaphase

What is the role of the spindle fibers during mitosis?

• To produce energy for the cell during mitosis

• To store genetic information for the cell during mitosis

• To help the cell maintain its shape during mitosis

• To separate the chromosomes by attaching to the centromeres and pulling them apart to opposite poles of the cell.

What is cytokinesis and when does it occur in the cell cycle?

• Cytokinesis is the process of dividing the cytoplasm of a parent cell into two daughter cells. It occurs after the completion of mitosis or meiosis.

• Cytokinesis occurs during the S phase of the cell cycle

• Cytokinesis is the process of cell division that occurs before mitosis

• Cytokinesis is the process of dividing the nucleus of a parent cell into two daughter cells

Explain the process of prophase in mitosis.

• The process of prophase in mitosis involves the replication of DNA

• The process of prophase in mitosis involves the condensation of chromatin into chromosomes, breakdown of the nuclear envelope, and formation of spindle fibers.

• Prophase in mitosis is characterized by the formation of a new nuclear envelope

• During prophase in mitosis, the chromosomes disperse into chromatin

How does the number of chromosomes in the daughter cells compare to the parent cell after mitosis?

• The number of chromosomes in the daughter cells is double that of the parent cell.

• The number of chromosomes in the daughter cells is the same as the parent cell.

• The number of chromosomes in the daughter cells is triple that of the parent cell.

• The number of chromosomes in the daughter cells is half that of the parent cell.

What would happen if the cell cycle was not properly regulated?

• Uncontrolled cell division leading to tumor formation or cancer

• Improved cellular function

• Enhanced cell differentiation

• Decreased risk of genetic mutations
