Study Notes
Cell Cycle Phases
- S Phase: The phase when DNA is replicated, ensuring each daughter cell receives an identical set of genetic material.
- Interphase: Composed of G1 phase, S phase, and G2 phase; this is the longest phase of the cell cycle where the cell grows and prepares for division.
- Mitosis (M Phase): The phase of the cell cycle where cells actually divide, including both nuclear division (karyokinesis) and cytoplasmic division (cytokinesis).
Cell Division Decisions
- Restriction Point: The critical decision made during G1 phase that determines whether the cell will proceed to divide again.
- Chromatin Condensation: Occurs when chromatin folds and condenses to produce visible chromosomes as the cell prepares for mitosis.
- Genetic Duplication Phase: During the S phase, the genetic information in the nucleus must be accurately duplicated to maintain genetic continuity.
Cytoplasm Division
- Cytokinesis: The phase of the cell cycle that specifically involves the division of the cytoplasm following nuclear division, resulting in two separate cells.
Major Cell Cycle Decisions
- G1 Phase Decision: A major decision point occurs during G1 phase regarding whether the cell will proceed with the division process.
Overview of Phases
- Phases Including Interphase: The term for the overall cell cycle structure includes Interphase, First gap phase (G1), Synthesis phase (S), and Second gap phase (G2).
- Short Duration Phase: The cell cycle includes a phase during which cells spend very little time, encompassing G1 phase, S phase, and G2 phase, prior to entering mitosis.
