Ribosomes are molecular machines that make proteins out of amino acids. They're made from RNA and proteins.
Ribosomes are divided into two subunits, one larger than the other. The small subunit binds to the mRNA, and the large subunit binds to the tRNA and amino acids. When a ribosome finishes reading the mRNA the two subunits split apart.
Ribosomes are found on the rough endoplasmic reticulum and in the cytoplasm.

Ribosomes read the information in RNA, then use it to make proteins. They do this by binding to a messeger RNA (mRNA) and use it as a template for the correct sequence of amino acids in a particular protein. The amino acids are attached to transfer RNA (tRNA) molecules, which enter a part of the ribosome and bind to the mRNA sequence. The attached amino acids are joined by another part of the ribosome, which reads the mRNA's sequence, producing a chain of amino acids (proteins).
