Detailed explanation-1: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).
Detailed explanation-2: -The correct order of phases of the cell cycle is G1 → S → G2 → M.
Detailed explanation-3: -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.
Detailed explanation-4: -So, the correct answer is ‘ G1→S→G2→M’
Detailed explanation-5: -By studying molecular events in cells, scientists have determined that interphase can be divided into 4 steps: Gap 0 (G0), Gap 1 (G1), S (synthesis) phase, Gap 2 (G2).
