D1.2.11—Mutations changing protein structure Topic Practice

D1.2.11—Mutations changing protein structure Topic Practice
IB Biology syllabusBiology SL/HLFirst assessment 2025

Practise tracing how DNA base substitutions can alter codons, amino acid sequences and protein structure, including sickle cell anaemia.

How this is tested

  • predict amino acid changes from mutated DNA sequences using codon information
  • explain how a base substitution can change haemoglobin structure in sickle cell anaemia
  • distinguish silent mutations from changes that alter the translated polypeptide
