Here's why:
* DNA contains the genetic blueprint: DNA holds all the instructions for building and maintaining an organism.
* Cell division requires copying DNA: When a cell divides, it needs to make a complete copy of its DNA so that each daughter cell receives a full set of instructions.
* Errors in replication can be harmful: If DNA is not copied accurately, the daughter cells might inherit genetic mutations that could lead to problems with their development or function.
Therefore, a cell must meticulously oversee the process of DNA replication to ensure that its daughter cells inherit a complete and accurate copy of its genetic information.
