Answer:
-To prevent mutations and keeping organisms in a healthy state.
Explanation:
DNA replication involves synthesis of daughter DNA molecules by using parent DNA as template. The cells have many methods to proceed error free replication, thus, DNA replication shows a highly accurate process.
It is because if one or more wrong nucleotide gets inserted into daughter DNA strand during replication, which does not get repaired, it will be lead to mutation in daughter cell. This mutation will pass to all progeny cells and can cause lethal consequences, such as development of cancer.
Thus, DNA replication without any mistake is important to prevent mutations and keeping organisms in a stable healthy state.
