ABSTRACT
Food security and quality products are inevitable for life sustenance. The population of human being is exponentially increasing, and this is creating food issues. There is one way to increase the cultivation area of agriculture or increase double crops cultivation in a year. For this new crop cultivars have to be produced, and this can be comprehended through using the latest biotechnological techniques. For this genetic engineering technique (GET) is very promising to cope this plethora of food security. The plants or other organisms produced through GET is currently being promulgated and organisms produced using this GET are called genetically modified organisms (GMOs). Albeit these GMOs have mitigated the issue of food scarcity, but it has also many other challenges of side effects with different paradigms. There is an issue to reveal and analyze biodiversity loss, and other health issues of GMOs. There is need to study the endogenous toxins in plants and/or other GMOs. This chapter encompasses the holistic preview of GMOs, their merits, and demerits.
GMOs are those which have foreign genes. Genes with desired characteristics are identified and isolated. Then these isolated genes are 90introduced into target organisms with the help of biological vectors. These transgenic organisms having genes of interest from other organisms incorporated into their genome are called GMOs. GMOs are essentially to be analyzed properly prior to use. The key features in context of use of GMOs may exhibit side-effects for health. The use positive use of GMOs is also beneficial to cope the needs of everlasting increment in the human world population. The GMOs are providing very promising scope in human history.
