Interpret this result is the chemical being tested is mutagenic.

What is mutagenic?

A mutation-causing agent (a change in the DNA of a cell). Mutagens can damage cells and result in diseases like cancer thanks to the DNA mutations they produce. Radiation from x-rays, ultraviolet light, and certain compounds are a few examples of mutagens.

In the field of genetics, a mutagen is a physical or chemical agent that permanently modifies genetic material, typically DNA, in an organism and raises the frequency of mutations above the background level of natural occurrence.

Physical, chemical, or biological mutagens can all be mutagenic agents. Mutagenicity is the property of a chemical that permits the induction of mutations or changes in DNA base pairs.
