1 answer

The property that is found only in cancer cells from the options provided is unregulated cell division.

While regulated gene expression, presence of mitochondria, and response to signals outside of the cell can be found in normal cells as well, cancer cells often exhibit uncontrolled proliferation that is not properly regulated by normal cellular mechanisms. This unregulated cell division is a hallmark of cancer.
