Fluid mosaic model of membrane structure was proposed by:

 # Fluid mosaic model of membrane structure was proposed by:

A. Watson and Crick

B. Edward H. Angle

C. G.V. Black

D. Singer and Nicolson

The correct answer is D. Singer and Nicolson.

The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded. The phospholipid bilayer gives fluidity and elasticity to the membrane. Small amounts of carbohydrates are also found in the cell membrane. The biological model, which was devised by SJ Singer and G. L. Nicolson in 1972, describes the cell membrane as a two-dimensional liquid that restricts the lateral diffusion of membrane components.
