Using DNA to Classify Life
... Until the mid-1970s, taxonomists usually classified life by morphology (shape). For example, a biologist might compare the structure of forelimbs of mammals. In recent years, biologists have also been able to compare the DNA and thus proteins in different organisms. A hypothesis known as the molecul ...

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.
