Cell Cycle and Cell Division Quiz

Study Notes

Cell Cycle Overview

The cell cycle is a series of events that lead to cell growth and division, essential for development and maintenance of all living organisms.

Main Stages of the Cell Cycle

Eukaryotic cells undergo two primary stages:
- Interphase: the phase where the cell prepares for division.
- M Phase (Mitotic Phase): includes mitosis and cytokinesis, where actual cell division occurs.

Interphase Details

Interphase consists of three sub-phases:
- G1 Phase (Gap 1): cell grows, synthesizes proteins, and produces organelles.
- S Phase (Synthesis): DNA replication occurs, resulting in two identical sets of chromosomes.
- G2 Phase (Gap 2): further growth and preparation for mitosis, ensuring all components are ready for division.

Control Mechanisms

Checkpoints are control mechanisms that monitor and regulate the progression of the cell cycle, ensuring proper replication and division of cellular components.
Key checkpoints occur at:
- G1 to S transition: checks for DNA damage and cell size.
- G2 to M transition: checks for DNA integrity and replication completeness.
- Metaphase stage during mitosis: ensures chromosomes are properly aligned before separation.

Cell Division Process

Cell division is called cytokinesis when a parent cell divides into two daughter cells, marking the final stage of the cell cycle after mitosis.
Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase, ensuring equal distribution of chromosomes to the daughter cells.
