Protein Practice
HS-LS1-1 Protein Synthesis Practice
I can statements for the HS-LS1-1 Unit:
● I can model the structure of DNA and describe the importance of it within our cells.
● I can construct an explanation of how genes code for proteins.
(____ points)
1. Here is one half of a DNA strand. Complete the other half by writing the complementary
base pairs.
A-T-G-C-C-A-T-A-T-G-G-G-T-A-A
2. You just wrote in the template strand of DNA. Use the template strand to transcribe a strand
of mRNA.
3. Write down the tRNA anti-codons that pair with the mRNA strand.
4. Use your codon wheel to write down the correct amino acid sequence from the mRNA
strand you created.
5. How can there be so many proteins when there are only 20 amino acids?
6. What are the stop codons? What do these tell us? Be specific.
7. What is the start codon? What does this mean? Be specific.
8. What is a codon? What strand do you find a codon on? Give an example of a codon.
9. What is an anticodon? On what strand can you find an anticodon?
