Answer:
Proteins seem better suited for storing genetic information because DNA is only made from 4 bases while proteins were made from 20 amino acids, Scientists thought that proteins could code for much greater variety in their amino acid sequence than DNA could in its nucleotide sequence.
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 <span>a gene that makes a </span>DNA<span> 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.</span>
