Study Notes
Cell Mitosis Overview
- Cell division comprises several phases, with interphase being the preparatory "in between" stage.
- During interphase, DNA exists as chromatin, which is a less condensed form, allowing for easy accessibility and replication.
Phases of Mitosis
- In prophase, chromatin condenses into visible X-shaped structures called chromosomes, essential for genetic material segregation.
- Metaphase is characterized by the alignment of chromosomes along the cell's equator, ensuring accurate distribution during division.
- Anaphase involves the separation of sister chromatids as they are pulled apart towards opposite ends of the cell.
Key Structures and Terms
- Mitosis is the process of cell division, resulting in two identical daughter cells.
- The nuclear membrane reappears during telophase, signaling the end of mitosis and the start of cellular reorganization.
- DNA replication occurs during interphase, crucial for ensuring that each daughter cell receives an identical set of chromosomes.
- Spindle fibers attach to chromosomes during metaphase and are vital for their movement, being formed in the prophase stage.
