... In the early 1970’s the unit membrane model was replaced by the fluid mosaic model. This model was first proposed by biochemists S.J. Singer and Garth L. Nicolson. The model retains the basic lipid bilayer structure, however, proteins are thought to be globular and to float within the lipid bilayer. ...
