Question

Certain cell types normally have several nuclei per cell. How could such multinucleated cells be explained? (A) The cell underwent repeated cytokinesis but no mitosis. (B) The cell underwent repeated mitosis with simultaneous cytokinesis. (C) The cell underwent repeated mitosis, but cytokinesis did not occur. (D) The cell had multiple S phases before it entered mitosis.

Answer 1

The formation of multinucleated cells can be explained perfectly by the option (C).

The sort of cell division known as mitosis occurs in somatic cells, or body cells, and involves the division of the parent cell into two daughter cells that share the same genetic makeup as the parent.

The process of mitosis in cells involves karyokinesis after which the cell goes through the process of cytokinesis. However, in case of multinucleated cells, they undergo the repeated mitosis but are not followed by the process of cytokinesis. And the the nuclei remain within the same cytoplasm, resulting in the formation of polynuclear cells.

Therefore, multinucleated cells are formed when the cell underwent repeated mitosis, but cytokinesis did not occur.
