Instructional Ideas
- Find out the maximum number of combinations using triplet coding
- Extend the idea by discovering the maximum possible if the activity used quadruplet coding instead
Classroom Considerations
- Relies on prior knowledge of DNA, DNA sequencing, and the 20 amino acids
Pros
- Connects math and science
- Provides closed captioning to support English learners
Cons
- None
