Question
1. You are part of a research group that wants to create a strain of humans resistant to
COVID-19 by inserting the "Corona Virus Resistance Gene" into the next generation of
humans.
In order to achieve this, you must design primers that would amplify the "Corona Virus
Resistance Gene."
a) Using the diagram provided, describe where the forward and reverse primers would
bind for amplification.
b) Would this construct use the same primers as Dr. Devlin used in his Growth Hormone
construct? Explain.

2. a) If you started with 5 DNA strands and the above diagram repeated for 9 cycles, how
th
many DNA strands would you have after the 9" cycle?
b) What would happen if you forgot to add dNTPs to the PCR reactions? Would any DNA
amplification occur?
3. A linear DNA molecule is digested by the LoIRI restriction enzyme that cuts DNA at four
different positions. After completing the restriction digest, you use gel electrophoresis to
visualize the DNA fragments. Answer the following questions.
a) How many bands would you observe after looking at your gel image?
b) During gel electrophoresis, what must you load onto your gel so that you can determine
the band sizes of each solution after running the gel?
