Fun Guy Science

How can one DNA change turn an orange flower petal purple? This phenomenon-based activity connects protein synthesis directly to a real visible trait. Students compare wild-type and mutant DNA sequences, decode through transcription and translation, and write a scaffolded CER argument explaining how the mutation changed the flower's petal color. What's Included: Wild-type and mutant pages, transcription and translation activity, codon chart, scaffolded CER writing prompt, projectable answer key,
