If DNA wasn't copied before cell reproduction, after the cells divide they would only have half the DNA that the original cell had.

And since we need all our DNA to tell the rest of the cell how to carry out all functions, with only half the DNA, a cell would shut down.

How does DNA reproduction take place?

In the nucleus of the cell, DNA replicates by the work of DNA Polymerase III copying the 5' to 3' strand while DNA Polymerase II ligates the Okazaki fragments on the 3' to 5' lagging strand.


Why is cloning a form of reproduction?

Sexual reproduction requires the mixture of DNAs from two different sources(i.e. you got a set of chromosomes from you mother and one from your father). Asexual reproduction involves a copying of just one source of DNA. In cloning, you take DNA from just one source and so it is asexual.

What is the importance of DNA replication in the cell reproduction?

DNA replication is significant in the reproduction of cells through the mechanisms of mitosis and meiosis. The DNA replicates so that there will be an extra DNA when the cell multiplies, allowing the "daughters" the chance to reproduce.
