📝 Understanding Cell Cycle & Cell Division for NEET & Board Exams
🔬 1️⃣ What is the Cell Cycle?
The cell cycle is the series of events by which a cell grows, duplicates its DNA, and divides into two daughter cells.

📌 Phases of the Cell Cycle:
✔ Interphase (G1, S, G2 Phase) – The preparatory phase for cell division.
✔ M Phase (Mitotic Phase) – The actual division process, either mitosis or meiosis.

🔬 2️⃣ Mitosis: The Process of Somatic Cell Division
✔ Prophase – Chromatin condenses into visible chromosomes.
✔ Metaphase – Chromosomes align at the center of the cell.
✔ Anaphase – Sister chromatids are pulled apart.
✔ Telophase – Two new nuclei form.

📌 Importance of Mitosis:
✔ Helps in growth and repair of tissues.
✔ Ensures genetic stability by producing identical cells.

🔬 3️⃣ Meiosis: The Basis of Genetic Variation
✔ Meiosis I & Meiosis II – Reductional and equational divisions.
✔ Crossing Over – Exchange of genetic material for variation.
✔ Formation of Gametes (Sperm & Egg Cells).

📌 Key Differences Between Mitosis & Meiosis:
✔ Mitosis produces 2 identical diploid cells, while meiosis produces 4 genetically unique haploid cells.
✔ Meiosis is essential for sexual reproduction and genetic diversity.

🔬 4️⃣ Regulation of the Cell Cycle
✔ Checkpoints (G1, G2, and M Checkpoints) – Ensure proper division.
✔ Cyclins & CDKs – Control the progression of the cell cycle.
✔ Apoptosis (Programmed Cell Death) – Prevents uncontrolled cell growth.

📌 Relevance to Cancer – Uncontrolled cell division leads to tumors.
