Quick answer

Cell division is how one cell becomes two. The cell first copies its DNA, then carefully splits that genetic material and its contents into two identical daughter cells. It's how living things grow, heal wounds, and replace old cells. A cell first duplicates its DNA.

Step by step

  1. A cell first duplicates its DNA.
  2. The copies are separated to opposite ends.
  3. The cell then splits into two identical cells.
  4. It powers growth, healing, and cell replacement.
