In this activity, biology students will enjoy solving puzzles as they review the two-step process of protein synthesis; transcription and translation. Three different DNA sequence puzzles are included. Students will review transcription by producing the mRNA sequence from the DNA, and then review translation by producing the amino acid sequence coded for by that mRNA. An extra step has been added as each amino acid codes for a letter of the alphabet. Using a special genetic code chart featuring this additional step, students will decode the secret message hidden within their assigned DNA sequence!
This printed teaching packet contains the following:
1. Three different puzzles (DNA sequences)
2. Teacher’s answer key for the three puzzles (mRNA sequences, amino acid sequences, and secret messages)
The only materials required for this activity are a pen or pencil! Please feel free to make as many copies as you need for your own students. I have found this activity to be an effective and fun way to help my kids master “DNA makes RNA and RNA makes protein.”
