Study Notes
Cell Turnover and Cell Division
- Cell turnover refers to the process of replacing old or damaged cells with new ones, which is dependent on cell division.
Types of Cell Division in Eukaryotic Cells
- There are two types of cell division in eukaryotic cells: mitosis and meiosis.
Cell Cycle
- Chromosomes replicate during the S phase (synthesis phase) of the cell cycle.
Role of Sister Chromatids in Mitosis
- Sister chromatids are identical copies of a chromosome that are joined together at the centromere, and they separate during mitosis, ensuring that each new cell receives a complete set of chromosomes.
Phases of Mitosis
- Mitosis consists of four phases: prophase, metaphase, anaphase, and telophase.
