The stage of mitosis pictured in the above image is metaphase.
<h3>What is mitosis?</h3>
Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.
Mitotic process is employed by living cells for growth and development. The process of mitosis is made up of the following stages:
- Prophase
- Metaphase
- Anaphase
- Telophase
Prophase is the first stage of mitosis, during which chromatin condenses to form the chromosomes.
Metaphase is the stage of mitosis during which condensed chromosomes become aligned before being separated.
According to the above image, chromosomes can be observed to be aligned at the centre of the cell, hence, the stage of mitosis pictured in the above image is metaphase.
