The process by which a cell duplicates into two daughter cells:

• A. Mitosis
• B. Nevus
• C. Cancer
• D. Skin tag

Answer: (A)

The process being tested is mitosis, the mechanism by which a somatic cell duplicates its genetic material and divides into two genetically identical daughter cells. After DNA is replicated, the cell undergoes nuclear division, then cytoplasmic division to complete two separate cells. This turnover and growth process is central to skin renewal, where basal-layer cells continually divide to replace older cells as they move upward and shed. The other terms describe skin conditions rather than a normal cell-division process: a nevus is a mole, a skin tag is a benign outward growth, and cancer refers to uncontrolled, often abnormal, cell proliferation. For completeness, meiosis is a different division that reduces chromosome number and produces four non-identical cells, not two identical daughters.
