The Discovery of Messenger RNA
Messenger RNA plays a key role in protein synthesis. This article looks at how the molecule was inadvertently discovered by Elliot Volkin and Lazarus Astrachan, who didn't realize the exact role of their 'DNA-like-RNA' find. It was left to other genetic researchers to make the connection.
