1. Using your keyboard, type in the letters that correctly pair with the DNA strand. The first letter
in the DNA strand is “A.” You should type “U.” REMEMBER: RNA DOES NOT HAVE
THYMINE, IT HAS URACIL INSTEAD.
2. Use the Universal Genetic Code chart to find the “met” amino acid (which codes for ‘start’).
What are the three letters that code for “met” ________.
3. Move your mouse over these three letters in the RNA strand.
4. Click and drag the correct amino acid from the chart to the RNA strand.
5. How many amino acids did you produce? __________
6. Write the names of the amino acids you produced:
_____________________________________________________________________________

Look at the Universal Genetic Code Chart to answer the following questions.
a. How many amino acids code for “met” (which is the start codon). ______________
b. How many amino acids code for “stop” __________
c. What is the amino acid that has the most forms (different codons) ______________
d. What could you infer about the importance of this amino acid?

Look at the sidebar with the drawing of transcription and translation to answer the following questions.

b. What part of the cell does translation occur in? ____________________________
