A scientist fused a mouse cell and a human cell, then treated the cell with specific antibodies covalently linked to colored fluorescent dyes (antibodies to mouse proteins were labeled green; antibodies to human proteins were labeled red). Forty minutes later, what will the researcher observe

The researcher observes a hybrid cell.

Explanation:

When a researcher perform an experiment in which he fused mouse cell with a human cell, a hybrid cell is formed. This fusion is done in the presence of Sendai virus which helps to combine two different types of cells with each other and produced a hybrid cell. These somatic hybrid cells contain the entire part of the mouse genome and a few number or parts of human chromosomes.
