The cell cycle is divided into two basic phases (i) Interphase (ii) M-phase (mitosis phase) The interphase is further divided into three phases (i) $G_{1}$-phase (gap 1) (ii) S-phase (synthesis) (iii) $G_{2}$-phase (gap 2) The correct sequence of a cell cycle is $G_{1} \rightarrow S \rightarrow G_{2} \rightarrow M$
