Mitosis and Cell Cycle Concepts

The video explains the cell cycle in eukaryotic cells, detailing the stages of interphase (G1, S, G2) and mitosis (prophase, metaphase, anaphase, telophase). It describes how cells grow, replicate DNA, and divide to form two genetically identical daughter cells. Cytokinesis, the division of the cytoplasm, completes the process.

What is the primary purpose of the cell cycle?

• To transport nutrients

• To produce energy

• To eliminate waste

• To grow and divide cells

During which phase of interphase does DNA replication occur?

• G1 phase

• S phase

• G2 phase

• M phase

What happens during the G1 phase of interphase?

• Cell growth and normal functions

• DNA replication

• Cytokinesis

• Chromosome separation

Which stage of mitosis involves chromosomes lining up at the cell's equator?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is the role of spindle fibers during mitosis?

• To separate sister chromatids

• To replicate DNA

• To dissolve the cell membrane

• To form the nuclear envelope

During which stage of mitosis do sister chromatids separate?

• Prophase

• Telophase

• Metaphase

• Anaphase

What marks the end of mitosis?

• Formation of spindle fibers

• Chromosomes condensing

• Nuclear envelope reformation

• Cytokinesis

What is the result of cytokinesis?

• One large cell

• Four daughter cells

• Two genetically identical cells

• Two identical nuclei

What is the final outcome of the cell cycle?

• Two genetically identical daughter cells

• Four genetically different cells

• One larger cell

• Two cells with half the DNA

Which phases occur during interphase?

• Mitosis, Cytokinesis

• Telophase, Cytokinesis

• G1, S, G2

• Prophase, Metaphase, Anaphase
