Question

cell division is not only for generating copy of DNA why​

Answer 1

Answer:

Given below

Explanation:

DNA replication must occur before cell division. So, that all newly produced cells have all the DNA of the original cell (except gametes of course). If DNA did not replicate (make exact copies), then new cells would not receive all the chromosomes and genes necessary for life processes.

Each new cell would only have half the needed chromosome. If it could survive each successive generation of cells would have fewer chromosomes and of course after a few divisions cells would receive none at all.
