Which of the following is not involved in synthesis of pyrimidines?: (A) Glutamine, (B) CO2, (C) Aspaic acid, (D) Glycine
Answer is D. The pyrimidine synthesis is a similar process than that of Purines(Purines Synthesis). In the de novo synthesis of Pyrimidines, the ring issynthesized first and then it is attached to a ribose-phosphate to for a pyrimidinenucleotide. Pyrimidine rings are assembled from bicarbonate, aspaate, and Ammoni
