Why does DNA replicate?

DNA replicates to ensure that each new cell, formed during cell division, has a complete set of genetic information. When a cell divides, it needs to produce two identical daughter cells, each with the same genetic material as the parent cell. DNA replication ensures that the entire genome is copied accurately, which is crucial for proper cell function, growth, and maintenance. Without replication, cells would not have the necessary instructions for their activities, and they could not pass on genetic traits to the next generation of cells.
