Quick Summary

A transgene is a gene that is taken from one organism and introduced into another through artificial techniques. This process, known as genetic engineering, allows for the creation of transgenic organisms, which carry the added gene (transgene) as a new part of their genome.12

Transgenic organisms can be developed for various purposes, including scientific research and improving commercial strains. For example, genes for insect toxins have been introduced into crops like corn and cotton to make them pest-resistant. Similarly, genes conferring herbicide resistance have been added to crop plants. In the pharmaceutical industry, biotechnology, which utilizes recombinant DNA technology, is employed to create transgenic bacteria, animals, and plants capable of producing commercial products such as pharmaceutical drugs and industrial chemicals. Gene therapy, a form of genetic engineering, aims to repair mutations causing genetic diseases by introducing a normal gene into an individual's genome.234
