you work for a biotech company that asks you to use heavy isotopes to label the proteins produced by a mutant bacterial strain. which element would you choose to label proteins but not any other macromolecule:
a.) C
b.) H
c.) O
d.) S
e.) N
Homework Answers
d) S
Sulphur, because other than protein no molecules contain sulphur. All other C, H, N, O are present in nearly every molecules like, DNA, RNA etc.

III. You isolate a new species of bacteria that only grows in the Antarctic. A wild type strain of this bacteria can synthesize its own alanine (alat) and its own tryptophan trp' ), both of which are essential amino acids. A mutant strain of the same bacterium cannot synthesize either of those two amino acids (ala trp'). You are interested in the degree of linkage between the ala and the trp genes in this new bacterial species. Fortunately, this species...
