This is the most advanced technology whereby the DNA of an organism has been modified to provide specific characteristics or functions. The term generally encompasses a class of techniques that are changing genetic material: gene editing, gene cloning, and recombinant DNA technology. Therefore, through gene manipulation, scientists can introduce new traits, enhance already existing ones, and correct genetic defects.

The most identified methods in the world of genetic engineering are CRISPR-Cas9. It has changed the world of research, allowing for the well-targeted change of the genome-that is to say, it can induce rapid changes in medicine, agriculture, and biotechnology areas.

Medicine produces gene therapy by genetic engineering seeking to cure or treat any form of genetic disorder with correction of faulty genes. For instance, the approach promises such things as curing cystic fibrosis and muscular dystrophy. Cell-based immunotherapies also use genetically modified cells selectively targeting with the aim of destroying cancerous cells.

This has, in agriculture, led to the cultivation of genetically modified crops with improved features aside from controlling pests and nutritional content with an expected yield. This has significantly reduced food security challenges and usage of pesticides.

In biotechnology, genetic engineering contributes to the production of pharmaceuticals, biofuels, and biodegradable materials. More importantly, scientists can engineer microorganisms to produce valuable substances more efficiently and sustainably. Overall, genetic engineering holds great promise but also raises concerns about ethics and safety that demand further research and regulation.
