Abstract

CRISPR technology has evolved significantly, focusing on precision in genome editing.

Early CRISPR-Cas9 systems were efficient in targeting specific DNA sequences but raised concerns about unintended edits.
The review discusses the transition of CRISPR from a prokaryotic discovery to its role in precision medicine.
Current applications of CRISPR include targeted therapies for genetic disorders.
Technical challenges such as off-target effects and delivery inefficiencies remain significant.
Ethical considerations regarding accessibility and long-term impacts are also highlighted.

Simplified

Since its introduction as a genome-editing tool, CRISPR-based technology has undergone rapid refinement, with precision emerging as a central focus of development. Early CRISPR-Cas9 systems demonstrated unprecedented ease and efficiency in targeting specific DNA sequences, but concerns over off-target effects and variable editing outcomes limited their broader application. This review outlines the progression of CRISPR from its discovery in prokaryotes to its application as a versatile tool in precision medicine, where it supports targeted therapies for genetic disorders in various ways. Although technical challenges, including off-target editing and delivery inefficiencies, persist alongside ethical considerations of accessibility and long-term consequences, CRISPR's ongoing refinements and innovations reflect a clear trajectory toward greater specificity, safety, and predictability, positioning CRISPR as an increasingly precise platform for both fundamental research and therapeutic use.
