Question

What forms the mitotic apparatus towards the completion of prophase?

Answer 1

Mitosis:

1. It is the process by which the duplicated genetic material of a parent cell is divided into two identical daughter cells.
2. The prophase is the beginning phase of mitosis.
3. Chromatin, the nucleus' mix of DNA and proteins, condenses during prophase.
4. The formation of visible chromosomes is the result of chromatin coils and compacts.

During completion of prophase:

1. Chromosomes are made up of a single, highly structured piece of DNA. Sister chromatids are chromosomes that have been duplicated and have an X shape.
2. The sister chromatids are two identical copies of DNA that are connected at a place known as the centromere.
3. The mitotic spindle, a structure, then begins to develop.
4. The mitotic spindle is composed of long proteins known as microtubules, which develop at opposing ends of the cell.
5. The spindle will be in charge of dividing the sister chromatids into two cells.
6. The mitotic apparatus, which comprises the asters, spindle, and traction fibres, is a temporary organelle-like structure visible during mitosis and meiosis.
7. It is a transient structure in a dividing cell that allows chromosomes to travel to the cell's poles, guaranteeing uniform distribution across daughter cells.
