Final answer:
A cell unable to divide due to lack of DNA can enter senescence, undergo programmed cell death, or potentially begin uncontrolled division, which can lead to cancer.
Step-by-step explanation:
When a cell becomes very large and is unable to divide due to the lack of DNA, it can respond in a few ways. The cell might enter an irreversible state of dormancy, which is called senescence. Alternatively, the cell might initiate programmed cell death, also known as apoptosis, which is a controlled process that leads to the elimination of the cell. Lastly, there is a possibility that the cell could enter a state of unregulated cell division, potentially leading to the formation of tumors and cancer. Therefore, the options provided in your question do not exactly represent what typically occurs in such a scenario. Cells do not undergo mitosis without DNA replication; instead, it's either a cessation of growth, programmed death, or dangerous uncontrolled division.
