Question

C. Fluid mosaic model proposed by Singer
and Nicolson replaced Sandwich model
proposed by Danielli and Davson?
Why?​

Answer 1

Explanation:

As per sandwich model it describes ‘lipo-protein sandwich’, as the lipid layer was sandwiched between two protein layers. so it's like sandwich appearance .

The fluid mosaic model expanded the Davson–Danielli model by including a lipid bilayer not cover by two protein layer instead protein are found as mosaic in lipid bilayer as transmembrane , peripheral membrance protein etc. in this fluidity shown by lipid bilayer or mosaic by protein.
