Question

what is mitosis?
a state where cells perform their normal functions without preparing to divide
the phase of the cell cycle where cells synthesize, or create, an identical copy of their dna
the phase of the cell cycle where a cell actively divides into two identical cells
the phase of the cell cycle where cells continue to grow and make final preparations to divide

Explanation:

Mitosis is a process in the cell cycle. It specifically refers to the phase where a cell actively divides. The first option describes interphase (not mitosis). The second option is the S - phase (synthesis of DNA). The fourth option is the G2 phase (pre - division growth). Mitosis is about cell division into two identical cells.

Answer:

The phase of the cell cycle where a cell actively divides into two identical cells.
