Mitosis

Mitosis is a process that results in two daughter cells with identical genetic material to the parent cell. It consists of several stages: prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, chromosomes become visible, and in prometaphase, the nuclear envelope breaks down. Metaphase is characterized by chromosome alignment, while anaphase involves the separation of sister chromatids. Telophase sees the formation of nuclear envelopes around daughter chromosomes. Finally, cytokinesis divides the cytoplasm, completing cell division.

What is the primary outcome of the mitosis process?

• Four daughter cells with different genetic material

• Two daughter cells with different genetic material

• Two daughter cells with identical genetic material

• Four daughter cells with identical genetic material

During which phase does the nuclear envelope break down?

• Metaphase

• Prophase

• Prometaphase

• Anaphase

What is the key characteristic of metaphase?

• Nuclear envelopes form

• Chromosomes align at the cell's equator

• Chromosomes condense into visible structures

• Sister chromatids separate

What happens to sister chromatids during anaphase?

• They align at the cell's equator

• They condense into chromosomes

• They form new nuclear envelopes

• They separate and move to opposite poles

How does cytokinesis differ between animal and plant cells?

• Both contract filaments

• Both form a cell plate

• Animal cells contract filaments, plant cells form a cell plate

• Animal cells form a cell plate, plant cells contract filaments
