Study Notes
Cell Division Phases
- Interphase: DNA replication occurs, preparing the cell for division.
- Prophase: Chromosomes condense, the nuclear membrane dissolves, and spindle fibers begin to form.
- Metaphase: Chromosomes align at the cell's equatorial plane and attach to spindle fibers.
- Anaphase: Chromosomes are separated into chromatids that move toward opposite poles of the cell.
- Telophase: New nuclear membranes form around each set of daughter chromosomes; chromatin begins to detangle.
- Cytokinesis: The cytoplasm divides, resulting in two distinct daughter cells.
Key Events in Cell Division
- DNA duplication only occurs during interphase.
- Individual chromosomes are no longer visible during interphase, telophase, and cytokinesis.
- The longest phase of the cell cycle is interphase, while metaphase is the shortest.
Roles and Structures
- Centrioles are responsible for producing spindle fibers and organizing chromosome movements.
- During metaphase, a cell will demonstrate a single line of chromosomes aligned at the center due to spindle fiber attachment.
Overview of Mitosis Stages
- Mitosis consists of four main stages: prophase, metaphase, anaphase, and telophase, each playing a critical role in cell division.
