Dartmouth researchers expose weakness of common parasite
.... Pyrimidines comprise two of the four DNA and RNA units
(nucleobases). "If we destroyed the ability of the parasite to make its pyrimidines de novo, we had no idea whether we could add pyrimidines to the parasite growth medium and actually grow the type of parasite mutant we were seeking. We simply had to...
Fundamental structural differences discovered in brains of autistic individuals
