Detailed explanation-1: -The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Detailed explanation-2: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Detailed explanation-3: -Answer and Explanation: Mitosis goes through cytokinesis once and meiosis goes through cytokinesis twice. This statement is true. Mitosis only has one round of division where the cytoplasm will divide only once.
Detailed explanation-4: -Final answer: The given statement is true.
Detailed explanation-5: -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).
