The universal genetic code - a language of life

What is the genetic code? 🧬

The genetic code is like the secret language our bodies use to build proteins. Imagine it as the programming language for life; just like you use English to communicate, your cells use the genetic code to 'talk.'

  • Bases in DNA/RNA: The language uses letters called bases. There are 4 types, so combinations of 3 (called codons) make 4 × 4 × 4 = 64 different 'words' or codons.
  • Meanings in the Code: Each of these 64 codons has a specific meaning:
    • Most codons tell the cell to add a specific amino acid (like a building block).
    • One says "Start!" 🚦
    • Three say "Stop!" 🛑

Why is it called universal? 🌍

Almost all living things use this exact code. Imagine if everyone on Earth spoke the exact same language; that's what life on Earth has done with the genetic code! Some small exceptions exist, like one of the 'Stop!' signs changing meaning, but they're rare.

 

Real-World Example: Think about emojis. 🙃 Everyone understands that a smiley face means happiness. It's a universal symbol, just like the genetic code is universal among living organisms.
