DNA must be copied within the nucleus to guarantee that each daughter cell obtains the right amount of chromosomes. Biomolecules and organelles must be replicated and distributed across the cells before a cell replicates and divides into new daughter cells via mitosis or meiosis. Why does DNA Replicate?ĭNA is the genetic substance that gives each cell its identity. Before dividing, a cell must copy its whole genome so that each ensuing daughter cell has its full genome. The method by which the genome’s DNA is duplicated in cells is known as DNA replication. As a result, DNA is a molecule that can be copied to produce almost perfect duplicates. And throughout the cell division process, all the data in a cell must be replicated properly. It starts with a single cell and ends up with billions of cells. Each cell carries all the DNA required to create the other cells. If you are wondering, what is DNA replication then the answer is that it is one of the most astounding things that DNA can perform.
