What are Singer and Nicolson known for?
(a) One-gene-one-enzyme hypothesis
(b) Plasma membrane modifications
(c) Fluid-mosaic model of plasma membrane
(d) Structure of DNA
The correct option is: (c) Fluid-mosaic model of plasma membrane
Explanation:
The structure of cell membrane can be described by the fluid-mosaic model, given by Singer and Nicolson (1972) According to them the cell membranes are considered to be quasifluid structures in which the lipids and proteins are in mosaic manner. This model considered the lipid protein association to be hydrophobic. The fluidity of the membrane is the result of this hydrophobic interaction.
