1. Visualising DNA replication and errors

Students interact with a 3D DNA model in Delightex that shows the DNA replication process. At specific points, the model highlights possible replication errors, such as mismatches or slippage. Students are asked to identify what type of mutation could result from each error and explain its potential effect.

Through interactive scenes, students observe how environmental factors such as UV radiation or chemicals can damage DNA. By activating different AR elements, learners see how these factors increase the likelihood of point mutations or larger DNA changes. This helps them understand the link between environment and genetic change.

3. Modelling chromosomal rearrangements

Using Delightex objects and scenes, students explore insertions, deletions, duplications, inversions, and translocations. Chromosome segments can be moved, flipped, or removed to visually demonstrate each mutation type. Students then discuss how these structural changes might affect gene function and organism health.

4. Mutation identification quiz

Students complete an AR-based quiz in Delightex where they classify mutation types based on short descriptions, diagrams, or animated sequences. This reinforces terminology and conceptual understanding in an interactive way.
