Question
The nuclear DNA content of a single sperm cell varies depending on the species of the organism.If the amount of DNA in a single sperm cell is 2.7 picogram(s), calculate the amount of DNA at different stages of meiosis or mitosis.
A). What would be the expected nuclear DNA content of a primary spermatocyte in the same organism?
B.) What would be the expected nuclear DNA content of a somatic cell (non-sex cell) in the G1 phase C.) What would be the expected nuclear DNA content of a somatic cell at metaphase?

Explanation / Answer
The amount of DNA vary at different stages of cell cycle. In a haploid sperm cell if the DNA content is 2.7 picogram, in diploid zygote it will be 5.4, In Go and G1 it is in 2N state i.e 5.4 picogram, In S phase it has 4 N content, that is 10.8 picogram. After which while entering mitosis it again enters in to diploid state 2N.
A. The DNA content of a primary spermatocyte is 2N state hence it will have 5.4 picogram
B. In non-sex cell in the G1 state it is in 2N state hence it will have 5.4 picogram
C. In somatic cell at metaphase it will be in tetraploid state hence it will have 10.8 picogram
