You're describing the process of DNA replication, which is a crucial step before cell division.

Here's why:

* Cell division is the process by which a single cell divides into two or more daughter cells.

* DNA replication is the process of creating an exact copy of the entire DNA molecule. This ensures that each daughter cell receives a complete set of genetic information.

So, the sequence of events is:

1. DNA replication: Duplicating the chromosomes.

2. Cell division: The cell divides, distributing the replicated chromosomes to the daughter cells.
