... Background: Large-scale mutations affect the entire chromosome or number of chromosomes. Point mutations are small-scale, but can seriously affect the gene being copied. There is an error in around every 100,000 base pairs copied, but there are proofreading abilities within the enzymes that copy the ...

Mutagen



In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
