Question 1
What is the importance of DNA copying in reproduction?
DNA contains the master copy of the data; the blueprints for how to make the proteins and other molecules that make the cell run. In its absence, cells would be unable to replicate make the molecules they need to survive, and thus would die. Now, cell replication is the process by which from one cell two cells are produced. Since the original single cell had only one set of DNA, it needs to copy it exactly 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. The probability of error arising from wrong DNA copying is literally one billionth. However, it is this probability that allows variations in the living organism to happen.
