Detailed explanation-1: -The Davson–Danielli model (or paucimolecular model) was a model of the plasma membrane of a cell, proposed in 1935 by Hugh Davson and James Danielli. The model describes a phospholipid bilayer that lies between two layers of globular proteins, which is both trilaminar and lipoprotinious.

Detailed explanation-2: -In 1935, Hugh Davson and James Danielli proposed a sandwich model in which the phospholipid bilayer lies between two layers of globular proteins.

Detailed explanation-3: -Danielli and Davidson in 1935, proposed sandwich model also called as Biomolecular leaflet model. According to this model, plasmalemma is a double phospholipid layer surrounded on either side by a layer of hydrated globular proteins in the form of “Protein-Lipid-Lipid-Protein".

Detailed explanation-4: -In 1935, Davson and Danielli proposed that biological membranes are made up of lipid bi-layers that are coated on both sides with thin sheets of protein and they simplified their model into the “pauci-molecular” theory.
