Study Notes
Mitosis Overview
- Mitosis is a process of cell division that results in two identical daughter cells.
- The spindle apparatus is crucial for moving chromatids during mitosis.
Spindle Apparatus
- Centrioles anchor the spindle fibers to ensure proper chromosome separation during cell division.
Phases of Mitosis
- Mitosis consists of four distinct phases:
- Prophase
- Metaphase
- Anaphase
- Telophase
Daughter Cells
- Mitosis, followed by cytokinesis, results in two daughter cells.
- Each daughter cell retains the same chromosome number as the original cell, maintaining genetic continuity.
Cytokinesis Timing
- Cytokinesis, the division of the cytoplasm, begins during the telophase of mitosis.
Chromosome Numbers in Animals
- A human cell with 46 chromosomes gives rise to daughter cells, each also containing 46 chromosomes.
- A dog cell with 72 chromosomes will result in two daughter cells, each with the same chromosome number of 72.
Nuclear Envelope
- The nuclear membrane dissolves during prophase, allowing chromatin to condense into visible chromosomes.
Chromatid Structure
- Centromeres hold individual chromatids together, ensuring correct segregation during cell division.
