- For your Senior Honor's Thesis, you need to make up a 100
ml 40% stock solution of acrylamide:bis acrylamide [29:1]. Your
advisor explains to you that the 40% solution contains a ratio
of 29 grams of acrylamide to 1 gram of bis acrylamide. You show
your advisor that the MW of acrylamide is 71.08 g/mole and bis
acrylamide is 154.17 g/mole. She gives you a hint: A 1% solution
is equal to 1 g/100 ml. Calculate how you would make this 40%
acrylamide: bis acrylamide [29:1] solution.
- The protein that you are purifying for your Senior Honor's
Thesis is about 50,000 kDa. Thus, you estimate that you need
an 8% acrylamide gel to separate it from other proteins. Calculate
how much of the 40% acrylamide solution that you made above
in problem #1 would be needed to make 20 ml of an 8% acrylamide
solution.
- Draw tryptophan, tyrosine, and phenylalanine. What are each
of these amino acid's three letter code? What are each of these
amino acid's one letter code?
- Draw the complete chemical structures of the peptide Pro-Arg-Lys
and also the peptide Ile-Pro-Val.
What is the one letter codes for each of these peptides?
- Who won the 1999 Nobel Prize in Medicine? What discovery did
this person or people make that it is worthy of a Nobel Prize?
How is this discovery related to what we are currently studying
in Biochemistry 3304?
