The source(s) of NH₂ groups in the synthesis of nucleotides is/are: A) aspartate B) glutamine C) glycine D) A and B E) A, B, and C

Question

Quizplus · Accepted Answer

NH2 groups in nucleotides are provided by aspartate and glutamine. Aspartate donates an amino group (NH2) during the synthesis of purines and glutamine donates an amino group (NH2) during the synthesis of both purines and pyrimidines. Glycine is not a source of NH2 groups in nucleotide synthesis. Therefore, the best choice is D, which includes the correct sources of NH2 groups.
