🔬 CELL CYCLE MCQ 📌
**Q: Duplication of chromosomes occurs in which phase of cell cycle?**

**OPTIONS:**
A) G-1
B) G-2
C) S phase ✅
D) Mitosis

**CORRECT ANSWER: C) S PHASE**

**EXPLANATION:** ⭐
**S Phase = DNA Synthesis Phase**
Is phase mein DNA replicate hota hai jis ki wajah se chromosomes duplicate ho jate hain.

**CELL CYCLE KI 4 MAIN PHASES:**
1. **G1 Phase** - Growth: Cell normal kaam karta hai aur bara hota hai
2. **S Phase** - DNA Synthesis: DNA duplicate hota hai. 1 chromosome → 2 chromatids
3. **G2 Phase** - Growth & Preparation: Cell division ke liye prepare hota hai
4. **M Phase** - Mitosis: Actual cell division hota hai

**DID YOU KNOW?** 💡
Before S phase: Chromosome = X shape, 1 DNA
After S phase: Chromosome = XX shape, 2 DNA = Sister chromatids

**IMPORTANT FOR:** Class 9, FSc, MDCAT, Entry Tests

**APNA ANSWER COMMENT KAREIN:** 👇
Sahi jawab diya ya nahi?
Comment "C" agar aapko pata tha!
