What is Mitosis?

Mitosis is the process by which a cell divides to produce two identical daughter cells, each with the same DNA as the original. It's how organisms grow, repair tissue, and replace old cells.

Key things to understand

  • 1One cell duplicates its DNA, then splits into two identical cells.
  • 2It proceeds through phases: prophase, metaphase, anaphase, and telophase.
  • 3It produces genetically identical cells (unlike meiosis, which makes sex cells).
  • 4It enables growth, healing, and the constant renewal of your body.

Frequently asked questions

What is the purpose of mitosis?
Growth, tissue repair, and replacing worn-out cells with genetically identical new ones.
How is mitosis different from meiosis?
Mitosis makes two identical cells for growth and repair; meiosis makes four genetically varied sex cells for reproduction.
What are the stages of mitosis?
Prophase, metaphase, anaphase, and telophase, followed by the cell splitting (cytokinesis).
