 * The Rough Endoplasmic Reticulum job
 * Add Phospholipids to proteins
 * Synthesize proteins from nucleotides
 * Build polypeptide chains
 * Fold proteins into their secondary structure
 * Add fatty acids to proteins
 * Discovery
 * It was Discovered by Albert Claude, a cell biologist from Belgium and his associate, Keith Porter. It was first noticed in the cytoplasm of chick embryo cells in the year 1945. In 1942 he decided that a new developed electron microscope would help him with his studies. This microscope showed the "lace-work" structure. This is how they later discovered the Endoplasmic Reticulum.
 * The surface is studded with protein-manufacturing ribosomes which gives it a rough appearance and that's how it got it's name. A Ribosome only binds to the ER when it begins to synthesize a protein. It is involved in protein production, protein folding, quality control and dispatch. Rough ER is found throughout the cell, but the density is higher near the nucleus and the Golgi apparatus
