Gene gun is a particle delivery system for transformation, especially in plants. In this technique a metal atom especially tungsten or gold is used as a bullet which is coated in small sequences of DNA. This gene gun releases bullets into the petri dish containing cells then particles containing DNA enters into the cells. The bullet also contains markers that confirm the entry of DNA into the cells. In this way, cells become genetically modified.
