Answer :
The question that will direct an investigation on how to develop an antibiotic that inhibits protein synthesis in bacteria is "How can the carboxyl (-COOH) terminus of a growing polypeptide chain be blocked?
It should be noted that in order to develop antibiotics, it's important for scientists to understand the growth and reproduction of bacterias.
A factor that contributes to the growth and reproduction of bacteria is protein synthesis. When scientists understand the synthesis of protein, they can then be able to develop antibiotics that will block bacteria when there's an infection.
