Question

The structural component of ribosome is

• A. t-RNA
• B. m-RNA
• C. r-RNA
• D. DNA

Answer 1

The correct option is C r-RNA

The structural component of ribosome is $r-RNA$.
Ribosomes are the cellular component that make proteins from all amino acids. Ribosomes are made from complexes of $RNAs$ and proteins. The number of ribosomes in a cell depends on the activity of the cell. Ribosomes are freely suspended in the cytoplasm or attached to the endoplasmic reticulum forming the rough endoplasmic reticulum. On an average in a mammalian cell there can be about 10 million ribosomes.
