WebbSolution. The correct option is D. 50S and 30S. All prokaryotes have 70S ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits. Suggest Corrections. Webb30 sep. 2024 · In eukaryotes, the sites of ribosome formation are the cytoplasm and the nucleus. The ribosome of eukaryotes is the 80S as opposed to the ribosome of prokaryotes, which is 70S. The 80S ribosome consists of a large subunit (60S) and a small subunit (40S). Each of these subunits is composed of ribosomal protein and rRNA(s).
