Expert Answer:


Dear Student,

 A basic event in reproduction is the creation of a DNA copy. Cells use chemical reactions to build copies of their DNA. This creates two copies of the DNA in a reproducing cell, and they will need to be separated from each other.


DNA copying is accompanied by the creation of an additional cellular apparatus, and then the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells.

The consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use that particular niche.

Reproduction is therefore linked to the stability of populations of species.


We hope that clarifies your query.
