Wild‑type E. coli cells can synthesize all 20 common amino acids, but some mutants, called amino acid auxotrophs, are unable to synthesize a specific amino acid and require its addition to the culture medium for optimal growth. Besides their role in protein synthesis, some amino acids are precursors for other nitrogenous cell products, such as the purine and pyrimidine nucleotides. Consider the three amino acid auxotrophs that are unable to synthesize glycine, glutamine, and aspartate, respectively. For each mutant, identify the nucleotide product or products which the cell would fail to synthesize by placing the nucleotide in the bin next to the auxotroph.
