Explanation:
Detailed explanation-1: -The prokaryotic ribosomes are of 70S type, unlike the eukaryotic ribosomes which are of 80S type. The 70S ribosomes are made of 50S and 30S subunits. Thus the correct answer is option D.
Detailed explanation-2: -In prokaryotes, the ribosomes are of 70S type and smaller compared to the 80S type found in the eukaryotes.
Detailed explanation-3: -Prokaryotic cells lack nuclear envelope, membrane-bound cell organelles like endoplasmic reticulum (ER), lysosomes, mitochondria, etc. They have DNA as genetic material, cell wall, cell membrane, and 70S ribosomes.
