What do you mean by mitotic apparatus?

What is mitotic apparatus Class 9?

Mitotic apparatus is the structure formed during mitotic cell division in order to split or separate the sister chromatids in between the daughter cells. >

What do you mean by mitotic spindle?

Definition. The mitotic spindle is the microtubule-based bipolar structure that segregates the chromosomes in mitosis. The poles of the mitotic spindle are made up of centrosomes and the chromosomes are lined up at the spindle equator to ensure their correct bi-orientation and segregation.

What do you mean by mitotic apparatus?

a temporary structure in a dividing cell that enables the chromosomes to move to the poles of the cell, thus ensuring their even distribution between the daughter cells. The mitotic apparatus is formed from macromolecules present in the interphase cell and from material synthesized before division. …

What happens in prophase stage of mitosis?

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

What is the mitotic spindle apparatus made of?

The mitotic spindle is a highly dynamic molecular machine composed of tubulin, motors, and other molecules. It assembles around the chromosomes and distributes the duplicated genome to the daughter cells during mitosis.

Where are mitotic spindles formed?

At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle.

In which type of cell division spindle is not formed?

All somatic cells form spindle fibres.

This single fibre helps in the division of the cytoplasm of cytokinesis full stop if spindle fibres are not formed then the cytoplasm of the cells will not separate.
