A single mature sperm cell of a particular diploid amphibian contains 3.8×10−12 g3.8 \times 10^{-12}\text{ g}3.8×10−12 g of DNA.
Calculate the mass of DNA contained in a somatic (body) cell of this amphibian during the G1\text{G}_1G1 phase of the cell cycle.
Name the type of cell division that produces these sperm cells.
