Mitosis Video

Which of the following represents the two main phases of the cell cycle?

• G1 and G2

• Interphase and Mitosis

• DNA synthesis and Cytokinesis

• Growth and Development

What is the primary purpose of cellular division in multicellular organisms?

• To allow organisms to reproduce sexually

• To replace old or damaged cells and facilitate growth

• To create new organisms from a single cell

• To produce specialized cells for different functions

In adult humans, which type of cell typically does not undergo division?

• Skin cells

• Digestive tract cells

• Muscle cells

• Blood cells

What is the main event that takes place during the S phase of Interphase?

• The cell undergoes an intense growth spurt

• The cell makes copies of all its genetic information

• The cell prepares for division by making more organelles

• The cell nucleus splits into two

How does cytokinesis differ between animal and plant cells?

• Animal cells form a cell plate, while plant cells pinch inward.

• Animal cells pinch inward, while plant cells form a cell wall in the middle.

• Both animal and plant cells form a cell plate.

• Both animal and plant cells pinch inward.

Which of the following events occurs during prophase?

• Chromosomes line up at the metaphase plate.

• Sister chromatids separate and move to opposite poles.

• DNA condenses into visible chromosomes, and the mitotic spindle begins to form.

• New nuclear membranes form around the separated chromosomes.

What is the correct order of the phases of mitosis, followed by cytokinesis?

• Metaphase, Prophase, Anaphase, Telophase, Cytokinesis

• Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

• Anaphase, Prophase, Metaphase, Telophase, Cytokinesis

• Telophase, Metaphase, Prophase, Anaphase, Cytokinesis

What is the primary function of the cell cycle control system?

• To ensure cells grow indefinitely without stopping.

• To regulate the timing and progression of cell division through checkpoints.

• To prevent DNA replication from occurring.

• To cause cells to divide uncontrollably, leading to diseases like cancer.
