Question

state importance of DNA copying in reproduction

Answer 1

Deoxyribonucleic acid (; DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproductionof all known living organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix.

Answer 2

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.
