Answer:
1. Aspartate and PRPP
2. Aspartate, glycine and glutamine
Explanation:
Aspartate is a precursor in both the synthesis of purine and pyrimidine. It aids in the formation of Carbamoyl Aspartate in pyrimidine synthesis while in purine, it contributes nitrogen 1 to the purine ring. PRPP is needed in the activation of ribose sugar in the purine nucleotide synthesis, while in that of pyrimidine, it aids in the conversion of orotate to OMP by adding phosphate group to orotate.
Aspartate, glycine and glutamine are precursors in the de novo synthesis of purine nucleotides. Aspartate contribts nitrogen 1, glycine cotributes C4, C5 and nitrogen 7 while glutamine contributes N3 and N9.
