Study Notes
Cell Division Overview
- Cells divide for growth, repair, and reproduction.
- Cytokinesis is the process of physically dividing a cell into two new cells.
- Mitosis refers to the division of a cell's nucleus into two new nuclei.
Key Terms
- Chromatin is a thin, fibrous form of DNA and proteins.
- Sister chromatids are identical structures produced from chromosome replication during the S phase.
Cell Cycle Components
- The cell cycle consists of two main parts: interphase and cell division.
- Interphase involves growth and preparation for mitosis.
- Cell division includes mitosis (nuclear division) followed by cytokinesis (cytoplasm division).
Interphase Stages
- G1 Phase (Gap 1): The cell recovers from mitosis after completing division.
- S Phase (Synthesis): DNA replication occurs, doubling the genetic material.
- G2 Phase (Gap 2): Prepares the cell for mitosis, replicating organelles and allowing further growth.
Mitosis Characteristics
- Mitosis begins after the G2 phase and concludes before the G1 phase.
- It involves a series of steps that ensure the proper distribution of chromosomes into daughter cells.
Additional Notes
- Interphase is the longest part of the cell cycle and includes three distinct phases: G1, S, and G2.
- Proper understanding of the cell cycle is crucial for insights into growth and repair processes in living organisms.
