Figure 16.2
-Refer to Figure 16.2. A branched metabolic pathway synthesizes two related amino acids D and F). If there is a genetic defect, resulting in a nonfunctional enzyme 3), how could you ensure that adequate amounts of the amino acid F are synthesized?

What molecule serves as a link between the information- containing macromolecule, DNA, and protein synthesis?
