Question

Fluid mosaic model of cell membrane was put forward by

• A. Danielli and Davson
• B. Singer and Nicolson
• C. Garner and Allard
• D. Watson and Crick

Answer 1

Answer: (B)

Singer and Nicolson

• The fluid mosaic model of the biomembrane or cell membrane was proposed by SJ Singer and GL Nicolson in the year 1972.
  
• According to this model, the protein molecules are embedded in the lipid bilayer.
• Thus, the proteins are seen as icebergs in the sea of lipids.
• It is the most acceptable model of the plasma membrane and its main function is to provide shape to the cell.
• So, the correct answer is 'Singer and Nicolson'.
