NAME:______________________DATE:________________PERIOD:____ Modeling Translation The center of the room is the nucleus. Inside the nucleus is the DNA. You are the single-stranded messenger RNA that is created inside the nucleus during transcription. You then leave the nucleus and find a ribosome, just as mRNA does. The ribosome uses your codons to create a protein during translation. You will then turn that protein into a sentence. Procedure: 1. You will be assigned a DNA sequence. Carefully copy the sequence onto your worksheet. Be sure to write the number of the sequence on your worksheet. Leave the DNA sequence in the nucleus. 2. While still in the center of the room, you will transcribe the DNA code into a single-stranded messenger RNA molecule. Introns are indicated by quotes (“). Write the mRNA sequence on your worksheet. 3. You are now ready the leave the nucleus and find a ribosome. Use the key at the ribosome to translate your mRNA sequence into proteins. Write the protein sequence on your worksheet. 4. Return to your desk and use the attached key to turn the protein sequence into a sentence. 5. Write the sentence on your worksheet. 6. Return to the nucleus for another DNA sequence until you have made four protein sentences. 1 1. DNA sequence (#_______) MRNA sequence: Protein sequence: Protein sentence: 2. DNA sequence (#_______) MRNA sequence: Protein sequence: Protein sentence: 2 3. DNA sequence (#_______) MRNA sequence: Protein sequence: Protein sentence: 4. DNA sequence (#_______) MRNA sequence: Protein sequence: Protein sentence: 3
