You played the role of a bioengineer perfectly. Here is what we learned today:
1. Mutations: These are errors in the DNA code. They can occur randomly or due to radiation. If left uncorrected, they can disrupt cell function.
2. Repair: Living cells have mechanisms to "fix" DNA. If they fail, diseases arise.
3. CRISPR/Cas9: The technology we simulated. It works like "molecular scissors," allowing scientists to find and cut out damaged genes, replacing them with healthy ones.
