Facts About Ribosome

Ribosome gets its name from "ribonucleoprotein particles" and "microsomes" which are both particles inside the cell. Richard B. Roberts suggested "ribosome" in 1958.
In 1955, George Palade, a cell biologist, along with Philip Siekevitz, discovered ribosomes and identified their function as making proteins.
Ribosome refers to ribonucleoprotein particles in sizes ranging from 35 to 100S.
