Answer:

I believe your question is about DNA replication, in which case the answer would be;

DNA replication must occur because existing cells will divide to produce new cells.

Step-by-step explanation:

DNA replication is important because the DNA basically needs to be copied before cell division so that each new cell receives a full set of "instructions" or parameters.
