The right answer is DNA is located in the nucleus.
The genome is the whole genetic material of an organism. It contains both the coding sequences, i.e. those that encode proteins, and the non-coding sequences. In most organisms, the genome is the DNA in the cells. However, in some viruses called retroviruses (eg HIV), the genetic material is RNA.
Cancerous cells go through interphase so fast, that they are constantly multiplying in mitosis.
