Q.31. What will be the amount of DNA in a pollen grain if its mother cell has 32 picogram DNA in phase?
(1) 16 pg
(2) 32 pg
(3) 8 pg
(4) 4 pg
Dear student.
The correct answer is (3) 8 pg.
Microspore mother cell (2n) undergoes meiosis and forms four haploid nuclei, which are known as microspores or pollen grains (n).
Microspore mother cell first divides and forms two haploid cells, which further divides and forms four haploid cells. During the division, the chromosome number becomes ½ whereas the amount of DNA becomes 1/4th.
Regards.
