Genetically modified (GM) crops are plants whose genetic material has been altered using biotechnology techniques, particularly genetic engineering, to introduce new traits that are not naturally found in the species. The aim of genetic modification is to enhance the desired characteristics of crops, such as improved resistance to pests, diseases, environmental conditions, or increased nutritional value. These modifications often involve the insertion of specific genes from other organisms into the plant's DNA to express new traits that can benefit agriculture, economy, and the food industry. The process of creating genetically modified crops begins with the identification of a gene responsible for a specific trait, such as resistance to a particular pest or improved drought tolerance. This gene is then isolated and inserted into the DNA of the target crop using various methods such as Agrobacterium-mediated transformation or gene gun technology. Once inserted, the modified gene is incorporated into the plant’s genome, enabling it to express the desired trait. Over time, these genetically modified plants are cultivated, tested, and approved for commercial production after extensive research to ensure safety, efficacy, and environmental compatibility. The most common genetically modified crops grown worldwide include maize (corn), soybean, cotton, canola, and rice. These crops have been genetically engineered to possess specific traits, such as herbicide tolerance, insect resistance, or enhanced nutritional content. For example, Bt cotton is a genetically modified variety that produces a protein from the bacterium *Bacillus thuringiensis*, which acts as a natural pesticide against certain insect pests, reducing the need for chemical pesticide applications. Similarly, glyphosate-resistant crops, often referred to as Roundup Ready crops, are engineered to withstand herbicides like glyphosate, allowing farmers to control weeds without damaging the crop. One of the key advantages of genetically modified crops is their potential to increase agricultural productivity. By introducing traits such as pest resistance, these crops can reduce crop losses caused
