b. Actin
c. Myosin
d. Lactase
____3. What happens when DMD muscles are exercised?
a. Nothing, they just don’t get any bigger
b. They tear just like regular muscles but don’t repair
c. Like regular muscles they repair just fine
____4. Which of the following is the correct order?
d. Translation -> transcription -> DNA → mRNA -->proteins -> amino acids
e. DNA -> transcription -> mRNA -> translation -> proteins -> amino acids
f. DNA -> transcription -> mRNA -> translation -> amino acids -> proteins
g. mRNA -> transcription -> DNA -> translation -> amino acis -> proteins
Matching:

13. Is therapy a good idea for someone with DMD? Support your answer with at least 2
good points. (2 points)
14. Explain how mutation occurs which results in a defective protein in DMD. Start with
how the DNA mutates and end with the protein. Include words such as: gene, mutated,
transcription, translation and dystrophin in your answer (5 points).
