    The correct sequence of different phases of cell cycle is

    A)  \[S-{{G}_{1}}-{{G}_{2}}-M\]

    B)  \[{{G}_{1}}-S-{{G}_{2}}-M\]

    C)  \[{{G}_{2}}-S-{{G}_{1}}-M\]

    D)  \[{{G}_{1}}-{{G}_{2}}-S-M\]

    Correct Answer: B

    Solution :

     The complete cell cycle contains a sequence of phases which are  Interphase which is further subdivided into \[{{G}_{1}}-\]phase or postmitotic gap, S-phase or synthesis phase and \[{{G}_{2}}-\]phase or premitotic gap respectively and  Dividing phase or M-phase (mitotic or meiotic phase) which comprises karyokinesis and cytokinesis. So, the correct sequence of phases in cell cycle is \[{{G}_{1}}\to S\to {{G}_{2}}\to M\]
