A terminator gene, also known as a suicide gene or lethal gene, refers to a specific type of genetic modification used in biotechnology. The terminator gene is designed to prevent genetically modified organisms (GMOs) from spreading and potentially causing harm in the environment. It acts as a self-destruct mechanism, ensuring that the modified genes cannot be passed on to future generations. Besides "terminator gene" or "suicide gene," other synonyms for this type of technology include "genetic use restriction technology" (GURT), "killer gene," and "trait protection system." Terminology can vary based on context and preference, but all refer to the same basic concept of genetically modifying organisms to limit their spread and potential impact.
