The mutagens that result in cancer damage DNA by (a) destroying the cells p53 gene directly thereby increasing cell production (b) weakening the DNA strand or interfering with base pairing (c) altering the cells pH and allowing increased cell productions (d) becoming a virus that attacks DNA directly l, impairing duplication

The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and, as a result, this will lead to formation of cancer.
