Detailed explanation-1: -The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Detailed explanation-2: -The cell cycle of a eukaryotic cell has three stages: interphase, mitosis, and cytokinesis.
Detailed explanation-3: -Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
Detailed explanation-4: -Interphase is defined by three stages: the first gap phase (G1), the synthesis (S) phase, and the second gap (G2) phase.
Detailed explanation-5: -Each step of the cell cycle is monitored by internal controls called checkpoints. There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2/M transition, and the third during metaphase. Positive regulator molecules allow the cell cycle to advance to the next stage.
