Why is it necessary for DNA to replicate?

DNA replication is necessary to ensure that when a cell divides, each daughter cell receives an identical copy of the genetic material. This process is crucial for maintaining the stability of an organism’s genome, as it prevents the loss of genetic information during cell division. Without DNA replication, the cells would not have enough genetic material to function properly, leading to errors in cell function and potential diseases. Replication is vital for growth, repair, and reproduction.
