What is the cell cycle?
The cell cycle is the life cycle of a eukaryotic cell which ends with cell division.

What are the two main components of the cell cycle?
The two main components of the cell cycle are interphase and the mitotic stage.
What occurs during interphase?
What occurs during interphase?
During interphase, the cells undergo periods of growth, make copies of its DNA, and begin to form the centrioles.

Study Notes
Cell Cycle Overview
- The cell cycle represents the life cycle of a eukaryotic cell and concludes with cell division.
Main Components of the Cell Cycle
- Comprises two key components: interphase and the mitotic stage.
Interphase Details
- Interphase includes periods of cellular growth, DNA replication, and centriole formation.
Stages of Interphase
- Consists of three stages:
- G1 phase: First growth phase where the cell enlarges.
- S phase: Synthesis phase focused on DNA replication.
- G2 phase: Second growth stage preparing for mitosis.
S Stage Significance
- The primary purpose of the S stage is to ensure accurate DNA replication.
Mitotic Stage Events
- The mitotic stage consists of two significant processes: mitosis and cytokinesis.
Cancer Definition
- Cancer is characterized by an accelerated cell cycle leading to uncontrolled cell division.
Major Phases of the Cell Cycle
- Two major phases: interphase and the mitotic phase.
Importance of Pre-DNA Replication Growth
- Cellular growth prior to DNA replication ensures sufficient DNA quantity for accurate replication.
Events of the S Phase
- Cells undergo DNA replication during the S phase of the cell cycle.
Mitosis Process
- Mitosis involves the division of the nucleus, where replicated chromosomes are distributed into two daughter nuclei.
Role of Spindle Fibers
- Spindle fibers attach to the centromeres of chromosomes and aid in separating them during cell division.
Meiosis Function
- The primary function of meiosis is to generate gametes for sexual reproduction.
