What was done
This chapter provides a narrative review detailing the history of CRISPR-Cas9 development from its origin as a prokaryotic adaptive immune system to its adaptation as a programmable genome-editing tool, discussing its clinical applications and ethical debates.
What was found
The abstract provides a qualitative summary of CRISPR-Cas9 biology and applications, noting its utility for targeted DNA cleavage, gene regulation studies, and therapeutic development for genetic diseases. No quantitative empirical findings or statistical results are reported.
Why it matters
It summarizes the developmental history and potential translational applications of CRISPR-Cas9 technology across molecular biology and human medicine.
Limits
As a narrative review, the publication presents no original experimental data or systematic study synthesis. Specific clinical efficacy, safety profiles, off-target rates, and delivery limitations are not quantitatively reported in the abstract.
