Mitosis Doodle Notes

Key Phases of Mitosis

Interphase

• Function: The cell grows and develops.
• DNA Activity: Chromosomes (DNA) are copied.

Prophase

• Chromosomes become visible.
• The nuclear membrane disappears.
• The nucleolus disappears.
• Spindle fibers attach to chromosomes.

Metaphase

• Chromosomes line up across the equator or middle of the cell.

Anaphase

• Chromosomes divide into two sets.
• Each half or set is pulled away to opposite sides of the cell.

Telophase

• Two nuclear membranes begin to form.
• Two cells begin to separate.

Cytokinesis

• Cytoplasm divides.
• Result: Two daughter cells with the same number of chromosomes.

Cell Cycle Summary

• Cells return to interphase after cytokinesis.
• Primary Stage: Eukaryotic cells spend most of their life in interphase.

Mitosis Overview

• Mitosis is a process of cell division in which a single cell divides to form two identical cells.

Important Terms

• Division: The process cells undergo in mitosis.
• Single: Refers to the original cell before division.
• Identical: Refers to the two new cells that are formed.
• Chromosomes: Structures that are copied and distributed during mitosis.

By understanding these stages and concepts, you gain insight into the critical process of cell division and the life cycle of eukaryotic cells.
