Final answer:
Antibiotics target specific sites in bacteria to inhibit their function and prevent bacterial growth. Examples include the binding of “β-lactam drugs” to penicillin-binding proteins, blocking the A-site by “Tetracycline,” and the targeting of RNA synthesis by “Rifamycins.”
Step-by-step explanation:
Antibiotics target specific sites in bacteria to exert their therapeutic function. For example, “β-lactam drugs” target and inhibit the binding of penicillin-binding proteins (PBPs), which interfere with bacterial cell wall synthesis. Another example is “Tetracycline” that blocks the A-site on the bacterial 70S ribosome, preventing protein synthesis. “Rifamycins” target RNA synthesis by binding to the DNA-dependent RNA polymerase.
