Here's the breakdown:
* DNA replication is the process of copying the entire DNA molecule within a cell. This happens before cell division to ensure that each daughter cell receives a complete set of DNA.
* Mitosis is the process of cell division itself. It involves the separation of the duplicated chromosomes (produced by DNA replication) and the division of the cytoplasm, resulting in two daughter cells.
Think of it this way:
* DNA replication is like making a photocopy of a book. The original book (DNA) remains intact, and you now have a copy (the replicated DNA).
* Mitosis is like taking the original book and the photocopy and splitting them into two separate books. Each book now contains a complete copy of the original information.
Therefore, DNA replication is a prerequisite for mitosis, but it is not the same as mitosis.
