Here's why:
* DNA Contains Genetic Information: DNA holds the instructions for building and maintaining an organism.
* Cell Division Requires Copies: When a cell divides, it needs to pass on a complete set of these instructions to each of its daughter cells.
* Replication Duplicates DNA: DNA replication is the process by which the entire DNA molecule is copied, creating two identical copies.
* One Copy Per Daughter Cell: Each daughter cell receives one copy of the replicated DNA, ensuring they have the necessary genetic information to function.
Without DNA replication, cell division would result in daughter cells with incomplete or incorrect genetic material, leading to developmental errors and problems.
