Question

Plasma membrane phospholipids are labeled with a fluorescent tag and then the phospholipids in one area are bleached with a laser beamto eliminate the fluorescent signal. what would one observe after the cell is incubated for a few minutes

Answer 1

When plasma membrane phospholipids are labeled with a fluorescent tag and then the phospholipids in one area are bleached with a laser beam to eliminate the fluorescent signal, one would observe that the bleached molecules would spread out sideways through the membrane and mix together with the unbleached molecules after the cell is incubated for a few minutes.
