Answer
Ribosome Structure and Classification
- ✅ A. True — Eukaryotic ribosomes are 80S, and prokaryotic ribosomes are 70S.
- ✅ B. True — Each ribosome consists of two subunits.
- ✅ C. True — 80S ribosome = 60S + 40S, and 70S ribosome = 50S + 30S.
- ❌ D. Incorrect — 20S is not a known subunit of ribosomes.
- ❌ E. Incorrect — 80S subunits are 60S and 40S, not 60S and 30S.
