If a cell in metaphase of mitosis is fused with a cell in the G$_1$ phase of the cell cycle, the second nucleus will also begin mitosis.
Which of the following is the MOST likely explanation for this behavior?
Since mitosis takes up most of the time in the cell cycle, it will dominate the newly created fused cell.
Molecules such as cyclins are in high concentration in the cytoplasm of a dividing cell and will signal the fused cell’s nucleus to undergo mitosis.
Spindle fibers from the first mitotic cell cannot distinguish between the chromosomes of the two nuclei.
The cell senses that it has too high of a surface area to volume ratio following fusion and begins division.
