Mitosis is the process of cell division that produces two identical daughter cells from a single parent cell. It is a relatively short phase compared to the rest of the cell cycle, which is why it only occupies a small percentage.
Here's a breakdown of the cell cycle and its phases:
* Interphase (90-95%): This is the longest phase where the cell grows, duplicates its DNA, and prepares for division. It consists of three subphases:
* G1 Phase: Cell growth and normal metabolic activities
* S Phase: DNA replication
* G2 Phase: Preparation for mitosis, including production of proteins needed for cell division
* M Phase (5-10%): This phase includes mitosis and cytokinesis.
* Mitosis: Division of the nucleus and its contents (chromosomes) into two identical nuclei.
* Cytokinesis: Division of the cytoplasm, resulting in two separate daughter cells.
Therefore, while the entire cell cycle is crucial, mitosis itself is a relatively short but critical step in the process of cell division.
