History behind ribosomes

WebbHistory: In 1953, George Palade observed ribosomes for the first time using an electron microscope. Structure of Ribosome: Ribosomes are non-membranous organelles that can be found in both bacterial and eukaryotic cells. Ribosomes are made up of two spherical subunits that are joined together to form a whole unit with a diameter of 200 Aº. Webb30S subunit of 70S ribosome possesses 21 protein molecules and 16S rRNA. 60S subunit of 80S ribosome has 40 protein molecules and three types of rRNAs- 28S, 5.8S and 5S. 50S subunit of 70S ribosome contains 34 protein molecules and two types of rRNAs— 23S and 5S. Proteins are both structural and enzymatic. Functions of Ribosomes:
