Question

You have fused a mouse cell and a human cell and then treated the cell with specific antibodies that are covalently linked to fluorescent dyes (antibodies to mouse proteins - green; antibodies to human proteins - red). What does the cell look like immediately after fusion?

1) The cell is half red and half green.
2) The cell appears to be yellow in color.
3) Both colors are uniformly distributed across the entire membrane.
4) Both colors are distributed in intermingled patches.

Answer 1

The cell would appear yellow in color immediately after fusion.

Step-by-step explanation:

The cell would appear to be yellow in color immediately after fusion. This is because when the cell is treated with specific antibodies that are covalently linked to fluorescent dyes, the red and green fluorescent tags would mix together and create a yellow color. This can be observed under a fluorescence microscope under UV light.
