What is the importance of DNA copying in reproduction

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. 

For evolutionary biologists, the most interesting difference is that meiosis has recombination, allowing mutations on different versions of the same chromosome to recombine onto a single chromosome, or vice versa, while in mitotic replication, the entire genome is a single linked haplotype and there is no chance for mutations to move to another haplotype (with the exception of gene conversion events).

Hope it helps you dear

Thank you

DNA transfer genetic information from one generation to other. During reproduction parents DNA combined and transfer in the baby.
