What is mitosis?

ScienceLesson on requestFree to read

Quick answer

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. One cell duplicates its DNA, then splits into two identical cells.

Key things to understand

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

People also ask

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).
