Full Answer

Following are the steps involved in mitosis and meiosis:

  • Prophase: The nucleus is preparing to divide.
  • Metaphase: The chromosomes line up in the middle of the nucleus and are ready to be pulled apart.
  • Anaphase: The chromosomes are physically split and are moved away from the center.
  • Telephase: The processes that occurred in prophase are reversed, and the new cells are formed.
