Detailed explanation-1: -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-2: -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).
Detailed explanation-3: -The correct order of phases of the cell cycle is G1 → S → G2 → M.
Detailed explanation-4: -The correct order of the cell cycle is G1, S, G2, M and possible exit into G0. During gap 1, or G1, the cell is growing and does its job in the body. During synthesis, or S phase, the cell duplicates its DNA to ensure that each cell resulting from a cell division will also have the correct amount of DNA.
Detailed explanation-5: -So, the correct answer is ‘ G1→S→G2→M’
