Cell Cycle and Mitosis Concepts

The video tutorial explains the cell cycle and stages of mitosis using movements to aid memory. It covers interphase, where the cell grows and DNA replicates, followed by mitosis stages: prophase (nuclear membrane breakdown and chromosome condensation), metaphase (chromosomes align at the equator), anaphase (sister chromatids separate), and telophase (new nuclei form). Cytokinesis divides the cell into two daughter cells, each re-entering interphase, continuing the cycle. The video encourages viewers to remember each stage through associated movements.

What happens during interphase?

• Chromosomes line up at the equator.

• The nuclear membrane breaks down.

• The cell grows and DNA is replicated.

• The cell divides into two daughter cells.

During which stage does the nuclear membrane break down?

• Metaphase

• Anaphase

• Prophase

• Interphase

What is the key event in metaphase?

• Two new nuclei form.

• Chromosomes line up at the equator.

• Sister chromatids separate.

• Chromosomes condense.

What occurs during anaphase?

• The cell grows to its maximum size.

• The nuclear membrane reforms.

• Sister chromatids separate and move to opposite ends.

• The spindle forms.

Which stage is characterized by the formation of two new nuclei?

• Telophase

• Anaphase

• Metaphase

• Prophase

What is the main event of cytokinesis?

• The cell grows and DNA is replicated.

• The nuclear membrane breaks down.

• Chromosomes line up at the equator.

• The cell divides into two daughter cells.

After cytokinesis, what phase does the cell enter?

• Anaphase

• Interphase

• Metaphase

• Prophase

Which of the following is the correct order of the stages of mitosis?

• Anaphase, Telophase, Prophase, Metaphase

• Prophase, Metaphase, Anaphase, Telophase

• Interphase, Prophase, Metaphase, Anaphase

• Metaphase, Anaphase, Telophase, Prophase
