Study Notes
Cell Cycle and Division
- DNA replication takes place during the S phase of the cell cycle.
- The phase where actual cell division occurs is called M phase (mitosis).
- Mitosis is also known as equational division.
- The time lapse between two successive M phases of cell division is known as the interphase.
- DNA replication is essential for growth, repair, and reproduction in cells.
Meiosis
- During metaphase I of meiosis, homologous chromosomes get attached to the spindles from opposite poles.
- The result of cytokinesis in meiosis I is two daughter cells, each with the diploid number of chromosomes.
- In some organisms, such as certain fungi and slime molds, cytokinesis does not immediately follow karyokinesis, leading to the formation of a multinucleate stage.
- During telophase II of meiosis, nuclear envelopes reform, and chromosomes uncoil to form chromatin.
- The outcome of meiosis II is four haploid daughter cells, each with unique combinations of alleles.
