🔬 PCR (Polymerase Chain Reaction)
PCR is a technique used to make millions of copies of DNA — like a biological photocopy machine! 📄➡️📄📄📄
🔥 3 Quick Steps:
1️⃣ Denaturation (95°C) – DNA strands separate 🧬➡️↔️
2️⃣ Annealing (50–65°C) – Primers attach 🎯
3️⃣ Extension (72°C) – New DNA is built by ???? 🧱🧬
⚡ After 30–40 cycles → Huge amount of DNA is produced 📈🧬
💡 Uses: Disease diagnosis 🦠, forensics 👣, research 🧪, and genetics 👨🔬
