Study Notes
Mitosis Phases
- Chromosomes begin moving toward the cell's equatorial plane during prometaphase.
Anaphase of Mitosis
- During anaphase of mitosis, sister chromatids separate and move to opposite poles of the cell.
Interphase
- Interphase is the longest stage of the cell cycle and is divided into three subphases: G1, S, and G2. During interphase, the cell grows, duplicates its chromosomes, and prepares for mitosis.
Mitotic Spindle Role
- The mitotic spindle, composed of microtubules, plays a crucial role in mitosis by attaching to chromosomes and pulling them apart to opposite poles of the cell.
Nuclear Envelope Reformation
- The nuclear envelope reforms around each set of chromosomes during telophase.
