The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes.Each human cell contains roughly two meters of DNA.he cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes.
After humans, the nature's relatively largest brain is that of the dolphin: 2 kg. A dolphin weighing 120 kg (280 pounds) has a 1.7 kg (4 pounds) brain; compared to its size, this is almost thrice than a chimp.
    Answer   The average human brain weighs three pounds (1.36 kilograms). The average female brain capacity is 79.3 cubic inches, slightly smaller than the male â¦ brain of 88.5 cubic inches. The largest human brains may be twice those of average size, but size has no relevance to brain performance.he average size of a donkey's brain is comparable to a human. The  donkey's brain is between 50 and 75 percent of the size of the  human brain.
