WebI. G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2) - The Cell “double checks” the duplicated chromosomes for error, making any needed repair. 2. Mitosis - nuclear/chemical events resulting in two daughter WebThe cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.
