The concept of transmembrane proteins was obtained from the results of which technique? Correct Answer Freeze-fracture replication

The concept that transmembrane proteins penetrate through the membrane was obtained from the results of freeze-fracture replication. In this procedure, a frozen solid tissue is fractured with a knife blade and metals are deposited on their exposed surfaces to form shadowed replica. This is viewed under electron microscope and it looks like a path strewn with pebbles, called as membrane-associated particles.
