Study Notes
Cell Cycle Overview
- The cell cycle consists of Interphase (G1, S, G2) and Mitosis (M Phase).
Interphase
- Interphase comprises three stages:
- G1 Phase: First Growth Phase
- S Phase: DNA is copied
- G2 Phase: Second Growth Phase
- At this stage, chromosomes are not visible and are replicated.
- Random DNA mutations can occur during replication in Interphase.
- Characterized as the organization phase and the reverse of prophase.
Mitosis Phases
- Mitosis involves division of the nucleus and DNA, detailed as follows:
-
Prophase:
- Nuclear membrane begins to fade.
- Chromosomes thicken and become visible.
- Spindle fibers start forming between centrioles.
-
Metaphase:
- Chromosomes align at the cell's equator.
- Spindle fibers attach to each chromosome at the centromere.
-
Anaphase:
- Centromeres divide allowing sister chromatids to be pulled toward opposite cell poles.
-
Telophase:
- Nuclear membrane reforms around chromosomes.
- Chromosomes uncoil and become less visible.
- Division furrow or cell plate formation occurs; cytoplasm is divided.
-
Prophase:
Cytokinesis
- Cytokinesis is the process where the cytoplasm divides, resulting in two separate daughter cells.
