Detailed explanation-1: -Therefore, bacterial cells, mitochondria, and chloroplast all contain the 70S ribosome.
Detailed explanation-2: -All prokaryotes have 70S (where S=Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits. Ribosomes play a key role in the catalysis of two important and crucial biological processes.
Detailed explanation-3: -Correct option: C. Explanation: 70S ribosomes are present in prokaryotic cells, chloroplast and mitochondria.
Detailed explanation-4: -There are mainly two types of ribosomes found, these are 70S ribosomes and 80S ribosomes. Complete answer: 70S ribosomes are found in prokaryotic cells and the chloroplast. 70S ribosomes are smaller in size that comprises two units. These are the large unit and small units.
Detailed explanation-5: -Ribosomes. Ribosomes found in eukaryotic organelles such as mitochondria or chloroplasts have 70S ribosomes-the same size as prokaryotic ribosomes. However, outside of those two organelles, ribosomes in eukaryotic cells are 80S ribosomes, composed of a 40S small subunit and a 60S large subunit.
