Question

What will be the amount of DNA in pollen grain if its mother cell has 32Pg DNA in G2 phase

Open in App

Solution

During G2 phase the DNA content of the cell doubles .
therefore, originally half of 32 , that is , 16 Pg was present.
since pollen grains are haploid in nature . so they will have half the amount present originally.
so 8 Pg dna is present in pollen grains.
