Start studying USMLE Mnemonic Biochemistry. De novo Pyrimidine Synthesis in Apicomplexa 685 20.3.1.1. So Think, " Pyrimidines can be CUT out from Purines". 1 out of every 5 questions on the USMLE® Step 1 Exam test your understanding of basic sciences ().This means that learning biochemistry is a make-or-break factor in achieving a competitive score and opening the door into your dream residency.. We report on the synthesis, stacking, and pairing properties of a new structural class of size-expanded pyrimidine nucleosides, abbreviated dyT and dyC. 2005 Jan 7;70(1):132-40. This page is meant to link students to more specific topics within biochemistry. Synthesis of the pyrimidines is less complex than that of the purines, since the base is much simpler.
