WebSolution. 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. WebRibosomes. Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit …

Web80S ribosome 1. They occur only in eukaryotic cells. 2. They occur inside the cytoplasm of eukaryotes either freely or attached to ER. 3. The ribosomes are larger in size with a length of (300—340 A) and breadth (200—240 A). 4. The sedimentation co-efficient is 80. 5. They are comparatively heavier, 4.0—4.5 million Daltons. 6. Eukaryotic ribosomes are also known as 80S ribosomes, referring to their sedimentation coefficients in Svedberg units, because they sediment faster than the prokaryotic ribosomes. Eukaryotic ribosomes have two unequal subunits, designated small subunit (40S) and large subunit (60S) … See more Ribosomes are a large and complex molecular machine that catalyzes the synthesis of proteins, referred to as translation.
