G2 phase occurs directly after DNA synthesis is completed in S-phase. During this phase cells grow in size, prepare for and synthesize proteins that will be required for cell division in M-phase. In G2 phase, cells also make sure that the DNA was properly replicated in S-phase and repair any DNA damage.
g2 phase
G2
Cells in G2 phase have a diploid set of chromosomes, which is twice the number found in gametes (haploid cells). In humans, this means that 46 chromosomes enter G2 phase.
When DNA replication is completed, the cell enters the G2 phase. G2 phase is usually he shortest of the three phases of interphase. During the G2 phase, many of the organelles and molecules required for cell division are produced. When the events of the G2 phase are completed, the cell is ready to enter the M phase and begin the process of cell division.

G2 phase
M Phase
10 chromosomes in the G2 phase, as the DNA is replicated during the S phase of the cell cycle.

G2 phase -
The three main parts of interphase are G1 phase, S phase, and G2 phase. During G1 phase, the cell grows and performs its normal functions. In S phase, the cell replicates its DNA. Finally, in G2 phase, the cell prepares for cell division.
