Study Notes
- Musique: topic is growth and reproduction in living organisms, specifically focusing on cells and their growth cycles.
- Cells are the basic structural and functional units of all living organisms, possessing a genetic heritage in the form of DNA.
- Cells reproduce conformally through a process called mitosis or meiosis.
- Mitosis involves the continuous process of chromosome reproduction, with cells not all being in mitosis at the same time.
- Mitosis is divided arbitrarily into four phases: prophase, metaphase, anaphase, and telophase.
- Prophase: the nuclear envelope disappears, chromosomes begin to appear, and a mitotic spindle forms.
- Metaphase: chromosomes align along the equatorial plane, becoming the shortest, thickest, and most individualized.
- Anaphase: each chromatide of each chromosome separates and migrates to opposite poles of the cell.
- Telophase: chromosomes decondense, new nuclear envelopes form, and two distinct cells develop, each with the same genetic information as the original cell.
- During interphase, the genetic material (DNA) is distributed and the cell grows, with different phases like G1, S, and G2.
- G1: cell growth phase post-division.
- S: DNA replication phase, where the DNA quantity is multiplied.
- G2: preparation phase for mitosis, where organelles multiply.
- Growth and DNA replication occur before mitosis.
- During interphase, the genetic material is present in a less dense, granular form called chromatin.
- Mitosis ensures the reproduction of identical daughter cells with the same genetic information.
