Would you expect to find multiple bands after electrophoresis of the impure GFP or the purified GFP?
Homework Answers
Answer: Impure green fluorescent protein (GFP) consists of contaminant proteins along with GFP. Purified GFP consists of only GFP protein without contaminant proteins. Hence, running a impure GFP on electrophoresis gel forms multiple bands that consists of GFP and contaminant proteins, whereas pure GFP forms single band.

5. Suppose you started with 10 g of impure compound A which was 80% pure, and after recrystallization you recovered 5 g of pure A. Calculate percent recovery. (5 points) 6. Should recrystallization increase or decrease the melting point range of the product you purified in class? Why? (5 points)

After pouring the SDS polyacrylamide gel, you realize that instead of 2 ml, you used 4 ml of 30% acrylamide/bisacrylamide solution for the preparation of the separating gel (in both cases for 5 ml, total gel volume). How would this affect the separation of your proteins during SDS PAGE? Explain your answer! b. You have to remake the gel and are now making sure just to add...

. You have just isolated a new bacterium species, it has the same DNA as other organisms, but replicates its DNA conservatively. Show the DNA bands you would expect to see if you carried out the Meselson-Stahl experiment for this organism. The bacterium will initially be grown on 15N and then switched to N. 14N DNA 5N DNA After 1 After 2nd replication replication
