During g2 phase the DNA content gets doubled than the original.
At G2 phase:
In S phase DNA replicates.
No. of DNA molecule in G2 will be =8
No. of chromosome=4 and as two DNA molecules are held at a common centromere. Or in other words each chromosome has two chromatids.
During Meiosis, there is no change in no. of DNA molecule and chromosomes in prophase and metaphase.
