Which mineral has the function of cell division?

• A. Calcium
• B. Magnesium
• C. Zinc
• D. Iron

Answer: (C)

Zinc is the mineral most closely linked to cell division because it acts as a key cofactor for enzymes involved in DNA synthesis and replication, and it supports the function of zinc-binding transcription factors that regulate genes needed for cell proliferation. This makes zinc essential during periods of rapid growth and tissue repair, since cells must divide and multiply efficiently. A deficiency in zinc can lead to impaired growth and delayed wound healing for this reason.

Other minerals support different roles: calcium mainly for bones, teeth, signaling and muscle function; magnesium as a general cofactor for many enzymes including those in energy metabolism; iron for oxygen transport and some metabolic processes. Yet none are as directly tied to the machinery of making new cells as zinc.
