You fuse a mouse cell and a human cell and then treat the cell with anti-mouse or anti-human protein-directed antibodies that are covalently linked to fluorescent dyes (antibodies to mouse proteins show green fluorescence; antibodies to human proteins show red fluorescence). What does the cell look like immediately after fusion?
A)The cell is half red and half green.
B)The red and green labels are uniformly distributed across the entire membrane.
C)The red and green labels are distributed in intermingled patches.
D)The cell appears to be yellow in color.
E)The cell appears to be brown in color.

Immediately after fusion, the proteins from the mouse cell and the human cell have not yet had time to mix, so the cell would show distinct halves - one half labeled with green fluorescence (mouse proteins) and the other half with red fluorescence (human proteins).
