Your DNA repair system will fix mutations before cancer is form. From this information what can you conclude?

Because the repository of genetic information in each living cell, its integrity and stability are essential to life. So there for a chemical entity subject to assault from the environment, and any resulting damage, if not repaired, will lead to mutation and possibly disease. Perhaps the best-known example of the link between environmental-induced DNA damage and disease is that of skin cancer, which can be caused by excessive exposure to UV radiation in the form of sunlight (and, to a lesser degree, tanning beds).

Explanation:

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
