Question

which of the following best describes the mechanism of action of the antibiotic streptomycin? multiple choice it disrupts protein synthesis in resistant bacteria. streptomycin creates mutations in bacteria which cause them to become resistant. it disrupts protein synthesis in nonresistant bacteria. streptomycin inhibits cell wall synthesis in all bacterial species.

Explanation:

Streptomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit of non - resistant bacteria, interfering with the initiation complex formation and causing misreading of mRNA codons, thus disrupting protein synthesis in nonresistant bacteria. It does not create mutations to cause resistance, nor does it inhibit cell wall synthesis. And it doesn't target resistant bacteria in terms of disrupting their protein synthesis as its main action is on nonresistant ones.

Answer:

It disrupts protein synthesis in nonresistant bacteria.
