Draw the molecular structure of a tripeptide chain. Indicate which amino acid was added first (assuming it was translated by a ribosome) by numbering the R groups as R1, R2, and R3 (you do not need to draw the structures of actual R groups for specific amino acids).

“Fana Lube” is a regional chain that provides a standard service for performing oil changes and basic checkups on automobiles. The chain has a standard that says the average time per car for this service should be 15 minutes. There is considerable variability in times due to differences in layout of engines, degree of time pressure from other jobs, and many other sources. As a result, the management of the chain decided to study if the standard is being met...
