1. Explain why DNA fragments can be separated using an electric current. How does the size of the fragment affect how far it
travels? [31]
2. Using the original MRNA strand below, analyze the other MRNA strands to determine what kind of mutation is presented.
(write out your amino acid sequence for each)
ORIGINAL MRNA: 5- AUG UAC GCU CCA AGU UAG -3
a. 5'- AUG UAC GCu cCC AGU UAG - 3' [2 1]
b. 5'- AUG UAC GCu CCA GU UAG -3' [2 1]
c. S- AUG UAGC GCU CCA AGU UAG -3 (2 ]
3. Using the picture below, explain which strand Okazaki fragments would be formed on, and why. [21]

4. Draw a picture of a TRNA molecule. The anticodon for this TRNA molecule is CAU. Include labels for :5', 3', anticodon and
amino acid. [4 C]
5. You were hired by Oakville Police Services to collect and analyze samples of DNA from a crime scene. Unfortunately, you
only found one hair from the suspect at the crime scene. Your team was hoping to use any samples to conduct several DNA
tests, but will not have enough DNA from the one hair. How could you produce more of the DNA from the sample? Is this
process the same as DNA that occurs in living cells? [5 1]
