IB Diploma Biology HL, topic D1
Molecules (Continuity and change)
How DNA is copied, how its base sequence is used to make polypeptides, and how changes to that sequence arise and can be made on purpose. The group covers DNA replication with PCR and gel electrophoresis, protein synthesis, and mutation and gene editing.
