In the S-phase of cell cycle, the amount of DNA doubles. So in S-phase, 8 picogram will double as 16 picogram. And then G2 phase will occur.

Calculating DNA content in different phases of the cell cycle
Introduction:
In the cell cycle, DNA replication occurs during the S phase, while the G2 phase is the period between DNA replication and the onset of cell division. The amount of DNA in a cell varies during the different phases of the cell cycle.
Given information:
The average DNA content of a group of cells immediately following mitosis is 8 picograms.
Calculating DNA content:
Since DNA replication occurs during the S phase, the amount of DNA doubles after this phase. Therefore, the amount of DNA in the cell at the end of the S phase would be 8 picograms x 2 = 16 picograms.
During the G2 phase, the cell prepares for cell division. The DNA content remains the same as in the S phase, 16 picograms in this case.
Therefore, the amount of DNA found at the end of the S and G2 phase would be 16 picograms.
Conclusion:
The amount of DNA in a cell varies during the different phases of the cell cycle. The DNA content doubles after the S phase and remains the same during the G2 phase. In this case, the amount of DNA found at the end of the S and G2 phase would be 16 picograms.
