Study Notes
Cell Division: Mitosis and Meiosis Overview
- Mitosis is a cell division mechanism primarily occurring in non-reproductive cells, while meiosis occurs in cells participating in sexual reproduction, specifically germ line cells.
- The eukaryotic cell cycle consists of distinct phases: Interphase (G1, S, G2 phases), Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
- During mitosis, a division of the nuclear contents occurs, with four distinct stages: Prophase, Metaphase, Anaphase, and Telophase.
- Cytokinesis occurs at the end of mitosis, resulting in the formation of daughter cells by either actin filaments contracting in animals or the formation of a new cell wall in plants.
- Meiosis is a reduction division resulting in the formation of gametes, achieved through two key events: meiosis I, which separates homologous chromosomes, and meiosis II, which separates replicated sister chromatids.
- Meiosis I consists of Prophase I, Metaphase I, Anaphase I, and Telophase I, while Meiosis II includes Prophase II, Metaphase II, Anaphase II, and Telophase II.
- Meiosis involves synapsis, where homologous chromosomes pair up and crossing over occurs, leading to the final amount of genetic material passed to the gametes being halved.
- Eukaryotic cells undergo mitosis for growth and repair, while meiosis is essential for sexual reproduction, resulting in the formation of haploid gametes.
- Diploid organisms have homologous pairs of chromosomes in somatic cells, while haploid organisms have only one set of chromosomes.
- Mitosis and meiosis are the two mechanisms by which eukaryotic cells divide their DNA into daughter cells.
