Questions and Answers

Which phase of mitosis involves chromosomes lining up across the equator of the cell?

Anaphase
Prophase

Flashcards

Prophase

The phase where chromosomes condense and become visible, the nuclear membrane dissolves, and spindle fibers form.

Metaphase

The phase where chromosomes align at the center of the cell, ready for separation.

Anaphase

The phase where sister chromatids separate and move to opposite poles of the cell.

Telophase

The phase where the nuclear membrane reforms, chromosomes uncoil, and the cell starts to divide.

Study Notes

Mitosis Stages

Prophase:
- Centrioles move to opposite cell poles.
- Chromatin condenses into visible chromosomes.
- Nucleolus shrinks and disappears.
- Chromosomes begin aligning at the cell equator.
Metaphase:
- Spindle fibers manipulate chromosome movement.
- Chromosomes are precisely aligned at the metaphase plate (cell equator).
- Chromosomes are highly condensed and visible.
Anaphase:
- Sister chromatids split at the centromere, forming two identical single-stranded chromosomes.
- Spindle fibers shorten, pulling separated chromosomes to opposite poles.
- A complete set of chromosomes is present at each pole by late anaphase.
Telophase:
- Nuclear membranes reform around each set of chromosomes.
- Nucleoli reappear.
- Chromosomes uncoil to revert to chromatin form.
- Spindle fibers break down.
- Two distinct nuclei are visible.
- Cytokinesis begins.
Cytokinesis:
- Cytoplasm and organelles divide.
- Mitosis is completed.
