What is the primary difference between prokaryotic and eukaryotic ribosomes?
Show answer and explanation
Correct answer: Prokaryotes use 70S ribosomes; eukaryotes use 80S.
Prokaryotic ribosomes are 70S (comprising 30S and 50S subunits), while eukaryotic cytoplasmic ribosomes are 80S (comprising 40S and 60S subunits). This difference is the basis for the selective toxicity of many antibiotics.
