DNA and RNA are two of the most important molecules in biology. They carry the instructions of life, but they are not the same. Let’s break them down step by step in a simple way.
“Diagram comparing DNA and RNA: double helix vs single strand, bases, sugars, stability, and functions.”
🔬 What is DNA?
- Full name: Deoxyribonucleic Acid
- Shape: Famous double helix (twisted ladder)
- Function: Stores the genetic code for all living things
- Bases: A, T, C, G (A pairs with T, C pairs with G)
🧩 What is RNA?
- Full name: Ribonucleic Acid
- Shape: Usually single-stranded
- Function: Helps read and use DNA instructions (messenger, builder, regulator)
- Bases: A, U, C, G (U replaces T)
📊 Key Differences Between DNA and RNA
| Feature | DNA | RNA |
|---|---|---|
| Sugar | Deoxyribose | Ribose |
| Strands | Double-stranded | Single-stranded |
| Bases | A, T, C, G | A, U, C, G |
| Main Role | Stores genetic information | Transfers and uses genetic information |
| Stability | More stable | Less stable |
✨ Why It Matters
DNA is like the master plan of life. RNA is like the messenger and worker that helps turn that plan into real proteins. Without both, life could not exist.
