In mice, there are viruses that are known to cause cancer. You have a pure preparation of virus DNA, a pure preparation of DNA from the chromosomes of mouse cancer cells, and pure DNA from chromosomes of normal mouse cells. Virus DNA will specifically anneal with cancer-cell DNA, but not with normal-cell DNA. I then explore the possible genetic significance of this observation, its significance at the molecular level, and its medical significance.© BrainMass Inc. brainmass.com September 24, 2018, 9:47 am ad1c9bdddf - https://brainmass.com/biology/cell-and-molecular-biology/understanding-dna-structure-viruses-cancer-5179
