D1.2.9—Using genetic code table Topic Practice
IB Biology syllabusBiology SL/HLFirst assessment 2025

Practise reading genetic code tables to translate mRNA or DNA-derived sequences into amino acid chains accurately.

How this is tested

  • determine amino acid sequences by reading mRNA codons in the correct order
  • distinguish DNA strands from mRNA options before using a genetic code table
  • apply start and stop codons when selecting a possible translated peptide
