The importance of optimal nutrition for human health
and development is well recognized. Crop yields are more impacted by adverse
environmental factors than by pests and diseases, such as drought, flooding,
excessive heat, and so forth. Finding methods to maintain high productivity
under stress and developing crops with improved nutritional value are therefore
two primary objectives of plant scientists. In order to satisfy the global need
for high-quality foods, genetically modified crops may show to be effective
complements to those made using traditional techniques. Genetically modified
crops can be utilized to raise yields and nutritional quality as well as their
tolerance to a variety of biotic and abiotic challenges. There have been some
biosafety and health concerns raised in relation to genetically modified crops,
but there is no reason to be worried about consuming products that have
undergone rigorous development and thorough testing. The objective of achieving
food security for both the present and future generations can be accomplished
by integrating modern biotechnology with conventional agricultural practices in
a sustainable manner. To fulfill the task of feeding the expanding global
population, climate change adaptable crops must be developed. By inserting
nucleic acid molecules produced by any method outside the cell into any virus,
bacterial plasmid, or another vector system to enable their incorporation
into a host organism in which they do not naturally occur but in which they are
capable of continued propagation, genetic modification refers to the creation
of new combinations of heritable material. One of the most common and
controversial results of modern biotechnology is genetically engineered
organisms. Recombinant DNA technology progress had followed the emergence of
genetic mechanisms and biological variability. Recombinant DNA is produced
synthetically by combining two or more DNA molecules into a single molecule. By
increasing yield and reducing reliance on chemical pesticides and herbicides,
genetically modified foods have the potential to address many of the world's
hunger and malnutrition issues as well as contribute to environmental
conservation and maintenance. Genetically modified plants can help commercial
agriculture overcome a number of present problems. One of the most dynamic and
innovative worldwide industries, the current market trends project benefits
consumers, major national economies, and growers as well.
