3. Which of the following processes involves the loss of a protein’s native structure?  denaturation renaturation hydration condensation

4. A protein solution is prepared by dissolving 350 µg of protein in 200 µL of water. A 150 μL sample of this solution is diluted to a total volume of 4.5 mL. How many mg of protein will be in a 2 mL sample of the diluted protein solution? Space to show your workings:

4.) If a mutation in an organisms DNA causes the resulting protein to possess an alanine residue to be in the 13th position instead of a glycine, what level(s) of the resulting protein's structure would likely be affected? Why? Why would the other(s) not be affected? 14:
