Why does DNA need to replicate?

DNA needs to replicate in order to ensure that each daughter cell receives an exact copy of the genetic information. During cell division (whether mitosis or meiosis), the cell must duplicate its DNA to pass on a complete set of chromosomes to the new cells. This is crucial for maintaining the stability of the organism’s genome and allowing proper growth, development, and cellular function. Without DNA replication, daughter cells would lack the necessary genetic material to function properly.
