IB Biology Topic D1.3: Mutations and Gene Editing Lessons

This lesson delivers structured, step-by-step lessons that guide students through every part of the IB Biology syllabus for D1.3 Mutations and gene editing. These lessons simplify complex ideas like molecular biology, evolutionary mechanisms, and homeostasis, while worked examples show how to approach IB-style questions.

Designed for both HL and SL learners, RevisionDojo lessons ensure students not only understand the theory but also know how to apply it in IB Paper exam situations.

With clear explanations, active learning checks, and a syllabus-first design, RevisionDojo makes revision less overwhelming and more effective.

D1.3.1 Gene mutations as structural changes to genes at the molecular level

D1.3.2 Consequences of base substitutions

D1.3.3 Consequences of insertions and deletions

D1.3.4 Causes of gene mutation

D1.3.5 Randomness in mutation

D1.3.6 Consequences of mutation in germ cells and somatic cells

D1.3.7 Mutation as a source of genetic variation

D1.3.8 Gene knockout (HL)

D1.3.9 Use of the CRISPR sequences and the enzyme Cas9 in gene editing (HL)

D1.3.10 Hypotheses to account for conserved or highly conserved sequences in genes (HL)
