in the viscous phospholipid bilayer ( 1 3 ). Membranes had been considered by the S-N model as a two-dimensional oriented solution of integral proteins. Among the novel aspects to be considered are: (i) the high density of proteins in the bilayer, that makes the bilayer a molecularly 'crowded' space, with important physiological consequences (ii) the proteins that bind the membranes on a temporary basis, thus establishing a continuum between the purely soluble proteins, never in contact with membranes, and those who cannot exist unless bilayer-bound (iii) the progress in our knowledge of lipid phases, the putative presence of non-lamellar intermediates in membranes, and the role of membrane curvature and its relation to lipid geometry, (iv) the existence of lateral heterogeneity (domain formation) in cell membranes, including the transient microdomains known as rafts, and (v) the possibility of transient and localized transbilayer (flip-flop) lipid motion. The SingerNicolson fluid mosaic membrane model (S-N model) ( 1) predicts lateral and rotational freedom and random distribution of molecular components in the membrane. However a number of features, the result of four decades of research, must be incorporated to obtain a valid, contemporary version of the model.

A)The plasma membrane is bound by basal bodies. Singer and Nicolson proposed the fluid mosaic model which stated that membranes were fluid and that the globular proteins were both peripheral and integral. Proteins stain darkly, suggesting that the dark pattern of the cytoplasm of the red blood cell is the distribution of proteins. This appearance supports the Davson-Danielli model. Proteins appear dark in electron micrographs and phospholids appear light.
