The mass of DNA molecules in somatic cells is 6 * 10^-9. What is the mass of DNA molecules before the onset of meiosis

The mass of DNA molecules in somatic cells is 6 * 10^-9. What is the mass of DNA molecules before the onset of meiosis and in anaphase of meiosis 1, explain the answer.

1) before the onset of meiosis I, the mass of m. DNA = 2 · 6 · 10 ^ −9 = 12 · 10 ^ −9 mg.
2) Since before the start of division in the s-period there was a doubling of the DNA molecule.
3) In the anaphase of meiosis I, the mass of DNA molecules is 12 · 10 ^ −9 mg. Since reduction division has not yet occurred, and all chromosomes are in one cell.
