Module 8

Translation concept

From codons to amino acids.

The genetic code

Each codon corresponds to an amino acid. AUG codes for Methionine. UAA, UAG, and UGA are stop codons. The full mapping is called the genetic code.

Python

genetic_code = {"AUG": "Met", "UUU": "Phe", "UUA": "Leu"}
print(genetic_code.get("AUG", "unknown"))

→ Met

Biology connection

Translation is how the cell builds proteins from the instructions in DNA. You are reading the same code the cell uses.
