Genetic Manipulation for Crop Improvement with an Advance Technique (CRISPR-Cas9)

Abstract

This article discusses how genetic manipulation—particularly CRISPR-Cas9—enables precise editing of DNA to improve crop traits. It explains the CRISPR mechanism, including Cas9-mediated DNA cutting and repair, and outlines applications in agriculture, medical science, ecology, and livestock improvement. It highlights ethical issues such as off-target effects, biosafety concerns, GMO release, biodiversity reduction, and regulatory challenges. The article concludes with future prospects including improved crop yields, enhanced resilience, and broader applications such as space exploration and climate change mitigation.
