The primary purpose of DNA replication is to produce copies of the genetic material contained in DNA before cell division. This ensures that each daughter cell receives a complete set of genetic instructions and is able to function properly.

DNA replication is essential for the continuation of life, as it allows cells to produce offspring and pass on their genetic information to future generations. It also ensures the accuracy of genetic information, as errors that occur during DNA replication can have a variety of effects on an organism.

In addition to its role in the continuation of life, DNA replication is also important in the study of genetics and molecular biology, as it allows researchers to understand how DNA is organized and how it is passed from one generation to the next.
