Study Notes
Cell Cycle Overview
- Cell cycle is a series of events for cell growth and division.
- Primary function is accurate DNA duplication and segregation into identical daughter cells.
- Crucial for growth, development, and tissue repair.
Interphase
- Longest phase; the cell prepares for division.
- G1 phase: Cell grows, synthesizes proteins for DNA replication, and performs regular functions.
- Synthesis phase: Cell replicates its DNA, resulting in two copies of each chromosome.
- G2 phase: Cell continues growth, produces proteins and organelles needed for mitosis, checks for DNA damage and ensures complete DNA replication.
M Phase (Mitosis and Cytokinesis)
- Involves the actual division of the cell.
- Mitosis: Separates replicated chromosomes into two new nuclei.
- Mitosis stages: Prophase, metaphase, anaphase, and telophase.
- Cytokinesis: Divides the cytoplasm, creating two distinct daughter cells.
Cell Cycle Regulation
- Tightly regulated checkpoints ensure accurate completion of each phase before the next.
- Checkpoints prevent errors like DNA damage or incomplete replication, which can lead to cell malfunction or cancer.
Importance of Cell Division
- Essential for growth, tissue repair, and reproduction.
- In multicellular organisms, replaces dead/damaged cells; in unicellular organisms, it's reproduction.
