Final answer:
Following DNA replication and cell growth, the cell typically enters the mitotic phase, where it divides to form two daughter cells with identical DNA.
Step-by-step explanation:
After the DNA of a cell has been replicated and the cell has fully grown and developed, it most likely enters the mitotic phase of the cell cycle. In the mitotic phase, the cell undergoes a process of division where the replicated DNA and cytoplasmic contents are divided, leading to the formation of two new daughter cells. This phase includes both mitosis, where the nuclear material is divided, and often cytokinesis, where the cell cytoplasm is divided. If the cell cycle is not disrupted by external or internal signals, the cell will proceed through these stages systematically.
