Name:__________________________________________________ Grade & Section:____________________ SAY IT WITH DNA: PROTEIN SYNTHESIS Objectives: To identify the amino acid that is coded by a given DNA sequence To analyze a simulated strand of DNA to determine the genetic code and base pairing of DNA Materials: Pen/Pencil Activity template copy Procedure: 1. Determine the secret message by transcribing and then translating the bases from the given strands of DNA below. 2. Use the dictionary to determine the letter that corresponds to each tRNA codon. 3. Record all your steps from transcription to translation, including the amino acid that corresponds to each tRNA codon.
