Question

A number of antibiotics attack prokaryotic protein synthesis, but not eukaryotic protein synthesis. Name two common antibiotics that work this way. What is their site of action and why don't they affect eukaryotic protein synthesis?

Answer 1

Answer:

Streptomycin and Erythromycine.

Streptomycin: inhibit protein synthesis by combining irreversibly with 30s subunit mRNA.Thus the normal synthetic sequences is disrupted.

Streptomycin does not stop protein synthesis in eukaryotic cells because it does not bind to eukaryotic ribosomes.

Erythromycine:The Erythromycine inhibits  protein synthesis through interference with the binding 50s subunit ribosome.

Erythromycin does not estop protien synthesis in eukaryotic cells because it does not binds to eukaryotic ribosome.Specificity towards prokaryotes relies upon the absence of 50S ribosomes in eukaryotes.

 Antibiotics block processes that occur in prokaryotic cells but not in eukaryotic cells that's why they not affect ekaryotes.

Explanation:

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors.

Antibiotics block processes that occur in prokaryotic cells but not in eukaryotic cells that's why they not affect eukaryotes.

There are different classes of antibiotics inhibit different steps of prokaryotic life cycle.

Streptomycin and Erythromycin are group of antibiotics that inhibit protein synthesis of bacteria.They are specifically effective against prokaryotes does not inhibit protien synthesis of eukaryotes.
