The cell-cycle is defined as the series of events that lead to DNA duplication and division of a cell to form daughter cells. The cell cycle is divided into interphase and M phase.
The interphase includes gap 1 (G 1) phase, S or synthesis phase, and gap 2 (G 2) phase, while M phase includes karyokinesis and cytokinesis.
The cells after M phase either goes for next cell division or G1 phase or for G 0 (gap 0) phase. The G0 phase is resting phase, in which cells show a quiescent state.
As memory cells are present in resting phase, till the next exposure of same antigen, these cells are in G0 phase of cell cycle.
