First replication of DNA occurs, after that division of the cell.
Explanation:
Before dividing into two daughter cells, the replication of genetic material i. e. DNA molecules occur in which same copy of DNA molecule is produces. After the replication process, the parent cell divides into two daughter cells having each the copy of DNA molecule. Binary fission is a type of asexual reproduction in which a single cell divides into two daughter cells and both the daughters cells are identical to the parent cell.
