ABSTRACT

Genetic engineering, empowered by revolutionary technologies like CRISPR/Cas9, has fundamentally reshaped modern biology and biotechnology. This paper examines the origins, mechanisms, and wide-ranging applications of CRISPR technology, from precision medicine to agricultural innovation. It examines the ethical considerations, regulatory frameworks, and societal impacts surrounding the use of genome editing tools. Key advances in high-throughput editing, base editing, and RNA targeting are discussed alongside the challenges posed by off-target effects and delivery system limitations. The review also delves into case studies showcasing CRISPR’s practical applications in health, agriculture, and fundamental research. Finally, the paper contemplates the philosophical and ethical implications of editing life at its most basic level and projects the future trajectory of genetic engineering in a world increasingly intertwined with biotechnology.

Keywords: CRISPR/Cas9, Genetic Engineering, Genome Editing, Gene Therapy, Biotechnology, Bioethics, Agricultural Biotechnology.
