Answer:
The mitotic phases alternate with interphase in the cell cycle. In interphase, the G1 phase occurs first where the cell grows while carrying out cell functions unique to its cell type. Then the S phase takes place where the cell duplicates its chromosomes. Next is the G2 phase, just before mitosis where the cell continues to grow and carry out its functions. After interphase, mitosis occurs, the first phase in mitosis is prophase where the chromatin becomes tightly coiled and the nucleoli disappear. Next is prometaphase where the nuclear envelope begins to fragment, and the two chromatids of each chromosome are held together by the centromere. After prometaphase is metaphase during which the microtubules and move the chromosomes to the metaphase plate at the equator of the cell. Next is anaphase where the sister chromatids separate. After anaphase, telophase occurs where the nuclear envelopes reform around the set of chromosomes located at opposite ends of the cell. Cytokinesis also occurs which is the division of the cytoplasm.
