Description

Transmission electron micrograph of a thin section of a preparation of isolated and plastic embedded rat liver polyribosomes (also known as polysomes). Polysomes associated with the endoplasmic reticulum are the sites of synthesis of proteins secreted into the RER cisternae and destined for export from the cell.
