Detailed explanation-1: -During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.
Detailed explanation-2: -The phases of interphase are the G1 phase (cell growth), S phase (DNA synthesis), and G2 phase (cell growth).
Detailed explanation-3: -Answer and Explanation: The correct answer choice is C. The nucleus replicates. Replication of the nucleus does not happen during interphase.
Detailed explanation-4: -’ There is interphase, prophase, prometaphase, metaphase, anaphase, telophase, and finally cytokinesis. Spindle fibers essentially exist during most of cell division. They form and exist through nearly all of the different phases.
