Answer 2

No. The amount of DNA is determined by the species of the organism, not the size of its cells. All cells of the same organism have the same amount of DNA, except for its gametes, which have half the amount of DNA. Also, as a cell grows after mitotic cell division, the amount of DNA remains the same for that species, and does not increase.
