INTRODUCTION
Toxins are only the substance that can hurt people or creatures. In interrelated genotoxicity alludes to the character of artificial compounds relating their capacity to make injure to hereditary material. The word mutagen refers to a substance that induces infectious changes in DNA structure connecting a group of genes or single gene. In hereditary qualities, genotoxicity is a term that depicts the property of artificial compounds relating to their capacity to make harm hereditary material [1]. Genotoxicity can prompt circuitous or direct consequences for the DNA including change enlistment, confused occasion initiation, and direct DNA harm which prompts transformations. It causes immediate, heritable changes that would be passed to people in the upcoming of cells [2]. Genotoxins contains chemical elements and radiation. Estimation of the genotoxicity effects of a diversity of materials for employ as drug mechanism is necessary. Approximately partially of all Pyrrolizidine alkaloids is classified as genotoxic and lots of are tumorigenic. A variety of chemicals have the probable to be genotoxic, and by addition, mutagenic. Beyond few techniques and methods can be accessible for genotoxicity testing.
