NEET BIOLOGY

Detailed explanation-1: -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-2: -Ribosomes have RNA and protein. They are sites of protein synthesis. The only cell organelle seen in a prokaryotic cell is the ribosome. Ribosomes in prokaryotes are of the 70s type.

Detailed explanation-3: -ribosome, particle that is present in large numbers in all living cells and serves as the site of protein synthesis. Ribosomes occur both as free particles in prokaryotic and eukaryotic cells and as particles attached to the membranes of the endoplasmic reticulum in eukaryotic cells.

Detailed explanation-4: -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.

Detailed explanation-5: -The large ribosomal subunit contains the aminoacyl transferase enzyme activity that connects amino acids to make a protein.
