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
