Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ cells have ribosomes
A
Eukaryotic
B
Prokaryotic
C
Both
D
None of the above
Explanation: 

Detailed explanation-1: -Ribosomes are found in both prokaryotic and eukaryotic cells.

Detailed explanation-2: -The prokaryotes have both 70s and 80S ribosomes.

Detailed explanation-3: -Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.

Detailed explanation-4: -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.

Detailed explanation-5: -The ribosomes in a eukaryotic cell generally have a Svedberg value of 80S and are comprised of 40s and 60s subunits. Prokaryotic cells, on the other hand, contain 70S ribosomes, each of which consists of a 30s and a 50s subunit.
