Final answer:
Binary fission is the term for the interval going from a single bacteria cell to two new daughter cells. It is a process of asexual reproduction where a single bacterium divides into two genetically identical daughter cells.
Step-by-step explanation:
The term for the interval going from a single bacteria cell to two new daughter cells is called binary fission. Binary fission is a process of asexual reproduction in which a single bacterium divides into two genetically identical daughter cells. During binary fission, the bacterial chromosome copies itself, and the cell enlarges before dividing into two new cells.
