Cell Cycle and Mitosis Quiz

Questions and Answers

What occurs during interphase?

Cell grows, performs its normal functions, and prepares for division.

What are the stages of mitosis?

Prophase (correct)

Anaphase (correct)

Metaphase (correct)

Telophase (correct)

What happens during prophase?

Nuclear membrane begins to disappear, DNA condenses and becomes visible, centrioles form and begin to form the spindle.

What occurs during metaphase?

Nuclear membrane is disintegrated, DNA lines up along the equator of the cell, spindles attach to chromatids. Signup and view all the answers

Study Notes

Cell Cycle and Mitosis

Interphase is the preparation phase for cell division, encompassing three stages:
- G1 (Gap 1): Cell growth, normal functioning, and development.
- S (Synthesis): DNA replication occurs, producing two identical copies.
- G2 (Gap 2): Preparation for division, including the production of centrioles and spindle fibers.
Mitosis is the process of cell division, consisting of five distinct stages:
- Prophase: Nuclear membrane starts to dissolve, DNA condenses and becomes visible, centrioles form, and spindle fibers begin to develop.
- Metaphase: Nuclear membrane completely disintegrates, DNA aligns along the cell equator, and spindle fibers attach to chromatids.
- Anaphase: Spindle fibers contract, pulling sister chromatids apart and moving them to opposite ends of the cell.
- Telophase: Spindle fibers disappear, nuclear membranes form around each chromosome set, resulting in two nuclei in one cytoplasm; the cytoplasm begins to pinch inward.
Cytokinesis follows mitosis, fully dividing the cytoplasm and resulting in two daughter cells, each with an identical copy of DNA.
