Two cells with different cell- surface markers are fused in the presence of polyethylene glycol (PEG). The cells are then placed at 0°C. What do you expect to observe about the individual cell markers?
A)The markers will essentially remain where they are, with little migration.
B)The markers will be endocytosed by the fused cell and then redistributed as fused markers.
C)Only one marker will disperse while the other remains stationary.
D)Both sets of markers will not mix, but will migrate to opposite poles from one another.
E)The markers will evenly disperse throughout both membranes.
