In a sample of cells, the DNA content immediately following mitosis is measured and is equal to 10 picograms of DNA per nucleus.
Rasek [7]

Answer:

1. At the end of S phase- 20 pg DNA

2. At the end of G2 phase-  20 Pg DNA

Explanation:

The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.

During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.

In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
