Phase; (also, second gap) a cell-cycle phase; third phase of interphase where the cell undergoes the final preparations for mitosis.

The G2 phase(second gap) a cell cycle phase and third phase of interphase where the cell undergoes final preparation for mitosis.

G2 phase or second gap phase is a cell growth phase in the which cells continue to grow to produce new proteins and prepare for final mitosis. It is the third stage of interphase, the first and second phase areG1(cell growth), S(synthesis). G2 phase is shorter that G1 and S for it only lasts between 3 to 4 hours in cells.
