Final answer:
Tetracycline antibiotics, such as doxycycline, target bacterial protein synthesis by binding to the 30S ribosomal subunit and blocking the binding of tRNAs.
Step-by-step explanation:
Tetracycline antibiotics are a class of antibiotics that target bacterial protein synthesis. They bind to the 30S ribosomal subunit and block the binding of tRNAs, thereby inhibiting protein synthesis. One example of a tetracycline antibiotic is doxycycline, which is used to treat gum disease, urinary tract infections, chlamydia, and gonorrhea, among other bacterial infections.
