A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.



Ribosomes are a part of the protein-generating factory in the cell. The ribosome itself is a two-subunit structure that binds to messenger RNA. And this structure acts as a docking station for the transfer RNA that contains the amino acid that will then become part of the growing polypeptide chain, which eventually becomes the protein.
