The human body uses the process of mitosis to repair an injury. how does mitosis in this process?

by producing identical cells

by producing different cells

by producing proteins to increase the size of the injured cells

by producing proteins to repair the injured cells

By producing identical cells.

Explanation:

Mitosis:

It is a cell division in which DNA of original cell duplicate and produce identical copies The two new cells are called daughter cells having same genetic code to parent nuclei.

Importance of mitosis:

Mitosis play very important role in both unicellular and multicellular organisms.

In unicellular organisms it help in asexual reproduction. It produces identical copies of parent cell. For example in amoeba mitosis help to produce its new individual through cell division.

In case of multicelluar organisms mitosis also play an important role.

Regeneration of injured tissues:

It helps to regenerate and repair the injured cells  by producing identical cells.

Growth:

It helps in the growth by producing new cells.  

Genetic stability:

In mitosis chromosomes splits and produce identical copies therefore daughter nuclei are identical to their parents. It helps to maintain the genetic stability.
