Question

what is the importance of DNA copying in reproduction

Answer 1

DNA contains the blueprints for how to make the proteins and other molecules that make the cell run. Without it, cells would be unable to make the molecules they need to survive, and thus would die.

Cell replication is the process of going from one cell to two cells. Since the original single cell had only one set of DNA, it needs to copy it so that both resulting cells have the DNA they need to survive. Reproduction of multicellular organisms is essentially a lot of cell replications, followed by differentiation of those cells. 

Answer 2

DNApresent in the nucleus contains all the information for the inheritance of feature from parents to offsprings.

DNA codes for all the proteins required by an individual.

Proteins control all the functions and the structure of an individual.

If DNA is not copied during reproduction , correct proteins will not be formed and the structure and functions of the individual will be entirely different.

Errors in dna copying lead to evolution

It helps in proper survival of organism by similar copying

It makes the organism look similar to each other

Hope it helps.
