Question

Match List I (Membrane model) with List II (Scientist) and select the correct answer using the code given below the lists: List I A. Protein-lipid-protein or sandwich model B. Unit membrane model C. Fluid-mosaic model List II 1. Robertson 2. Singer and Nicolson 3. Davson and Danielli
Options
A A-1, B-3, C-2
B A-2, B-1, C-3
C A-3, B-1, C-2
Correct Answer
D A-3, B-2, C-1
Correct Answer

Option C is the correct answer.

Detailed Explanation

The protein-lipid-protein (sandwich) model was proposed by Davson and Danielli (A-3). The unit membrane model, which described the trilaminar structure seen in electron micrographs, was proposed by Robertson (B-1). The fluid-mosaic model, the current accepted model, was proposed by Singer and Nicolson (C-2).

Hint

Match each membrane model to the scientist(s) most associated with its proposal.
