Detailed explanation-1: -Ribosomes are a specific target of some antibiotics since there is a significant difference in size and structure between eukaryotic and prokaryotic ribosomes: eukaryotic ribosomes consist of a 60S subunit and a 40S subunit, whereas prokaryotic ribosomes are composed of 30S and 40S subunits.
Detailed explanation-2: -The ribosomes in eukaryotic cells are 80S, with 40S and 60S subunits, and in prokaryotic cells: 70S with 30 and 50S subunits. The makeup of the locomotive structures (i.e., flagellum) also varies between prokaryotic and eukaryotic cells.
Detailed explanation-3: -Ribosomes are found in prokaryotic and eukaryotic cells; in mitochondria, chloroplasts and bacteria. Those found in prokaryotes are generally smaller than those in eukaryotes. Ribosomes in mitochondria and chloroplasts are similar in size to those in bacteria.
Detailed explanation-4: -Answer and Explanation: The answer is false. Eukaryotic ribosomes have a distinct shape compared to prokaryotic ribosomes. Eukaryotic ribosomes have an elongated body with a curved surface, whereas the prokaryotic ribosome has a spherical shape with no discernible structure on its surface.
