Question

Mitosis results in the formation of nuclei having .......... number of chromosomes. Fill in the blanks with appropriate words.

Answer 1

Mitosis is a process of cell division which results in the formation of 2 identical daughter cells.

Complete answer:
MItosis is a process in which a cell reproduces or duplicates itself. Two copies of a cell are produced which complete clones of the parent cell.
Mitosis is also called an equational division of cells. This means if the chromosome number of the parent cell is 2n, then the chromosome number of the daughter cells is also 2n.
In the cell cycle, the Mitotic phase comes after the synthesis and growth phase. The chromosome replication and the synthesis of mitotic spindle has taken place. After this, the Mitosis starts.
Mitosis takes place in somatic cells and as discussed above, the chromosome duplication has taken place prior to the start of mitotic division. This implies, that after division each cell contains a copy of chromosome set in its nucleus which is similar to the parent cell. This happens in all the successive generations therefore the mitotic progeny are genetically identical.

Additional Information:

After mitosis, cytokinesis takes place whereby the cytoplasm of the parent cell is divided into daughter cells each of which have a nucleus containing the same number and kind of chromosomes as the parent cell’s nucleus.
A single mitosis event can take from 70-180 minutes with Prophase being the longest one.
Mitosis is preceded by Interphase where a cell grows and replicates, thus preparing itself for mitosis.

Therefore, the answer is an equal or same number of chromosomes.

Note: Mitosis is a cell division process which helps in growth of new cells and replacing the damaged ones. It eventually helps in tissue growth and development of an organism.
