DNA:
🧫 Deoxyribonucleic Acid (DNA) is the hereditary material found in nearly all living organisms. It carries the genetic instructions that define how we grow, function, and reproduce. 🧍♂️🧍♀️
Structure:
🧱 DNA is made of molecules called nucleotides, each consisting of:
• A phosphate group ⚡
• A sugar molecule (deoxyribose) 🍬
• A nitrogenous base (A, T, G, C) 🧩
Double Helix:
🌀 James Watson & Francis Crick discovered the double helix model of DNA in 1953, showing two strands coiled around each other like a spiral staircase 🧬.
Functions:
📖 Storage of genetic information
🧬 Transmission of traits from parents to offspring
⚙️ Guidance for protein synthesis
Interesting Facts:
💡 The human genome contains about 3 billion base pairs!
If stretched out, the DNA in one human cell would be over 2 meters long! 😲
