Study Notes
Cell Cycle and Mitosis Overview
- Interphase consists of three main phases: G1, S, and G2.
- DNA replication occurs specifically during the S phase of interphase.
- The correct order of interphase subphases is G1 → S → G2.
Mitosis Phases
- Mitosis phases follow this order: Prophase, Metaphase, Anaphase, Telophase.
- Chromosomes become visible as distinct entities during Prophase.
- The nuclear envelope disintegrates during Prophase.
- During Metaphase, chromosomes align along the cell's equator.
- Sister chromatids separate during Anaphase, leading to eventual formation of daughter nuclei.
- Telophase is characterized by the reformation of the nuclear envelope.
Cellular Activities
- During interphase, cells perform basic functions necessary for survival.
- Replication of chromosomes takes place during interphase, specifically in the S phase.
- A cell spends the majority of its lifecycle in interphase.
Chromosomes and Sister Chromatids
- Chromosomes condense during Prophase.
- Sister chromatids are held together by a structure known as the centromere.
- Sister chromatids remain connected during Prophase and Metaphase, and are completely separated by Anaphase.
Key Definitions
- Interphase-s refers to the phase of the cell cycle where DNA replication occurs.
- Prophase marks the beginning of visible chromosome formation and nuclear envelope breakdown.
- Anaphase is the stage where sister chromatids are separated into individual chromatids, destined to become new daughter nuclei.
