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
