Correct Answer: B
Solution :
Robertson (1959) was first proposed the concept of unit membrane model. According to Robertson, the unit membrane consists of a bimolecular lipid leaflet sandwiched between outer and inner layers of protein, organized in the pleated sheet configuration, Protein-phospholipid -phospholipid - protien. Each unit membrane is \[75\,\overset{\text{o}}{\mathop{\text{A}}}\,(65-85\,\overset{\text{o}}{\mathop{\text{A}}}\,)\] thick. Such an arrangement was presumed to be basically the same in all cell membranes.You need to login to perform this action.
