Biology

A cell contains multiple nuclei with identical genetic information. This cell most likely formed by going through

(A) multiple rounds of mitosis, but no cytokinesis
(B) multiple rounds of the M phase, but no rounds of the S phase
(C) multiple rounds of cytokinesis, but no rounds of mitosis
(D) multiple rounds of the cell cycle, but no rounds of mitosis
(E) multiple rounds of the S phase, but no other phases of the cell cycle
  1. Correct Answer: A

    Explanation:

    A single cell with multiple nuclei must have undergone multiple rounds of mitosis, which is the replication of the nucleus. It did not, however, undergo cytokinesis, which is the division of a eukaryotic cell to form two daughter cells.
