The nucdlear DNA content of a single sperm cell varies depending on the species

Question

The nucdlear 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 2.5 picogram(s), calculate the amount of DNA at different stages of meiosis. Part A What would be the expected nuclear DNA content (in picograms) of the cell before DNA replication has occurred in Interphase I (before S phase) ? Submit Request Answer v Part B What would be the expected nuclear DNA content of a cell at metaphase 1? picograms Submit Request Answer

Explanation / Answer

Part A : 2.5 picogram will remain as there is no synthesis of dna and it remains same

Part B: now DNA doubles as synthesis has occured in metaphase so 2.5×2=5.0 picogram
