Flashcards
Interphase
Interphase
The period of the cell cycle when a cell grows and prepares for division; includes G1, S, and G2 phases.
Mitotic Phase
Mitotic Phase
The phase of the cell cycle where the cell divides into two daughter cells.
G0 Phase
G0 Phase
A period in the cell cycle where cells exist in a resting state and do not divide.

Study Notes
- Cell Cycle has two main parts: Interphase and the Mitotic phase
Interphase Divisions
- G1: Growth Phase
- S: Synthesizer, the cell duplicates DNA
- G2: Cell continues to grow while preparing for mitosis and cell division
- Mitotic Phase is the multiplier and creates two daughter cells
- G0: Cells stay dormant and do not divide
Mitosis: 4 Phases
- Prophase: Chromatin becomes tightly kindled, forming using 4 chromosomes, sister chromatids
- Anaphase: Sister chromatids of each chromosome separate at the centromere and are pulled apart by the spindle fibers, essentially dividing the replicated chromosomes into two separate sets that will eventually become part of two new daughter cells
- Metaphase: A phase of cell division when chromosomes align in the middle of a cell
- Telophase: The final stage of mitosis and meiosis, when a cell's duplicated DNA is separated into two identical daughter cells
- Cytokinesis
Vocabulary
- Asexual Reproduction: Offspring that is genetically identical to parent
- Binary Fission: Cell divides into two equal halves, resulting in two identical daughter cells that are also identical to the parent
- Meiosis: Unspecified information about the process
