Exploring the Stages of Mitosis

The video tutorial explains cell division, focusing on mitosis and the cell cycle. It details the stages of mitosis: prophase, prometaphase, metaphase, anaphase, and telophase, and describes the cell cycle phases: G1, S, and G2. The process of cytokinesis, where two new cells are formed, is also covered. The video emphasizes the importance of these processes for cell growth, replication, and function.

Why is cell division necessary for an organism?

• To grow, mature, and maintain tissues

• To produce energy

• To create food

• To eliminate waste

What is the first stage of mitosis?

• Metaphase

• Telophase

• Anaphase

• Prophase

During which stage do microtubules attach to chromosomes?

• Anaphase

• Prometaphase

• Metaphase

• Prophase

What happens during the S phase of interphase?

• The cell divides

• The cell grows to its full size

• DNA in the nucleus is replicated

• The cell finishes growing

Which stage of interphase is known for cell growth and biochemical functions?

• G2

• S

• M

• G1

What marks the beginning of prometaphase?

• Chromosomes align at the center

• Nuclear membrane breaks down

• Sister chromatids separate

• New nuclear membranes form

During which stage do sister chromatids align along the center of the cell?

• Anaphase

• Prophase

• Prometaphase

• Metaphase

What occurs during anaphase?

• Chromosomes condense

• Cell grows

• Nuclear membrane reappears

• Sister chromatids separate

What is the final stage of mitosis?

• Prophase

• Metaphase

• Anaphase

• Telophase

What process follows mitosis to complete cell division?

• Anaphase

• Metaphase

• Cytokinesis

• Prophase
