Final answer:
The steps of mitosis include prophase, metaphase, anaphase, and telophase. Each of these stages plays a specific role in ensuring that the genetic material is accurately divided between two daughter cells. Interphase is a preparatory phase and is not considered part of mitosis itself.
Explanation:
Steps of Mitosis
Mitosis is a crucial process where a single cell divides into two identical daughter cells. It consists of several distinct stages, each playing an important role in ensuring proper cell division. The steps of mitosis include:
- Prophase: This is the first stage where chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
- Metaphase: In this stage, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.
- Anaphase: Here, sister chromatids are pulled apart toward opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.
- Telophase: This final stage involves the reformation of the nuclear envelope around each set of chromosomes, followed by the uncoiling of the chromosomes back into chromatin.
The option interphase is not a step of mitosis; it is part of the cell cycle that occurs before mitosis begins, during which the cell prepares for division by replicating its DNA and organelles.
