What are Singer and Nicolson known for?

Options

AOne-gene-one-enzyme hypothesis
BPlasma membrane modifications
CFluid-mosaic model of plasma membrane
DStructure of DNA

Correct answer

C. Fluid-mosaic model of plasma membrane

Step-by-step solution

The most recent model of plasma membrane is fluid-mosaic model which was proposed by Singer and Nicolson in 1972. According to this model, the membrane does not have a uniform disposition of lipids and proteins but is instead a mosaic of the two. Further, the membrane is not solid but is quasifluid.
