Study guide test 2 Strategies of nucleotide synthesis: precursors, when is ribose added, how is ribose activated and added, what are first purines and pyrimidines made, how are the various forms of THF made and/or interconverted, regulation of purine synthesis (where are committed steps), how is a balance between AMP and GMP achieved, how do folic acid antagonists impair purine synthesis. • Pyrimidines: base is made before adding the ribose sugar • Purines: ribose is already present  suga...
