Ribosomes are small (20 X 30 nm) approximately spherical ribonucleoprotein particles. The ribosome is made up of two subunits - the large (A) and the small subunit (B). A Yale University research group, headed by Thomas Steitz, determined the structure of the large subunit. This subunit is composed primarily of two long RNA molecules, a genetic material similar to DNA and found in all cells and some ...
