The genetic material duplicates is the first step in binary fission

Explanation:

In the binary fission a parent cell gives rise to two daughter cells. In binary fission first the nucleus of the parent cell divides into two nucleus, then the division of cytoplasm takes place.

The process begins when the cell replicates chromosomes, and then moves the two DNA molecules apart, next when the cells have double in size a nex membrane and wall are deposited in the midsection.
