🔁 DAT Cell Cycle & Mitosis: Phases, Function, and Regulation

You’ll be tested on:

• Phases of the cell cycle

• What happens in each phase

• Checkpoint logic

• Mitosis vs. cytokinesis

Expect both diagram labeling and function matching questions.

🧪 Phases of the Cell Cycle

1. Interphase (Longest phase)

• G1: Growth & normal activity

• S: DNA replication (synthesis)

• G2: Preparation for mitosis

📌 Tip: DNA replication ONLY happens during S phase.

2. M Phase (Mitosis + Cytokinesis)

Stage	Key Events
Prophase	Chromosomes condense, spindle fibers begin to form
Metaphase	Chromosomes align at the cell equator (middle)
Anaphase	Sister chromatids pulled to opposite poles
Telophase	Nuclear envelopes reform; chromosomes decondense
Cytokinesis	Cytoplasm divides, forming two identical daughter cells

🔁 Checkpoint Summary

Checkpoint	Checks For	Controlled By
G1	Cell size, DNA damage	Cyclins, CDKs
G2	DNA replication success, damage	Cyclins, CDKs
M (Spindle)	Chromosome alignment & attachment	APC/C, cyclin degradation

🧠 DAT Question Examples

• “During which phase does DNA replicate?”

• “What checkpoint ensures chromosomes are aligned?”

• “What’s the difference between mitosis and cytokinesis?”

💡 Helpful Mnemonics for Mitosis

PMAT = Prophase, Metaphase, Anaphase, Telophase
G0 Phase: Resting phase for non-dividing cells like neurons
