An antibiotic like Streptomycin targets 70S ribosomes to inhibit bacterial protein synthesis. Why does this drug generally not interfere with protein synthesis in human cytoplasm?
Q1. An antibiotic like Streptomycin targets 70S ribosomes to inhibit bacterial protein synthesis. Why does this drug generally not interfere with protein synthesis in human cytoplasm?
Answer: Human cytoplasm contains 80S ribosomes
Explanation: Human cytoplasmic ribosomes are 80S, while bacteria have 70S. Mitochondrial ribosomes are tempting because they are 70S, but the drug's safety depends on cytoplasmic differences.
