Biology Question on cell cycle and cell division

The correct sequence of different phases of cell cycle is

A

S−G1−G2−MS-{{G}_{1}}-{{G}_{2}}-M

B

G1−S−G2−M{{G}_{1}}-S-{{G}_{2}}-M

C

G2−S−G1−M{{G}_{2}}-S-{{G}_{1}}-M

D

G1−G2−S−M{{G}_{1}}-{{G}_{2}}-S-M

Answer

G1−S−G2−M{{G}_{1}}-S-{{G}_{2}}-M

Explanation

Solution

The complete cell cycle contains a sequence of phases which are Interphase which is further subdivided into G1−{{G}_{1}}- phase or postmitotic gap, S-phase or synthesis phase and G2−{{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 G1→S→G2→M{{G}_{1}}\to S\to {{G}_{2}}\to M
