all the genetic material in one cell's nucleus is called what
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.n mammalian cells, the average diameter of the nucleus is approximately 6 micrometres (Âµm), which occupies about 10% of the total cell volume. The viscous liquid within it is called nucleoplasm, and is similar in composition to the cytosol found outside the nucleus.
