At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides?

Understand the Problem

The question is asking what essential process must occur before a cell divides at the end of the mitotic cell cycle, focusing on the necessary biological steps.

More Information

Before a cell divides during the mitotic cycle, the chromosomes must be copied during the S phase. This ensures each daughter cell receives an identical set of chromosomes.

Tips

Common mistakes include confusing chromosome replication with other cell structures or processes. Remember that chromosome copying is crucial for genetic consistency.
