What is Gene Editing?
Gene editing refers to targeted modification of specific DNA sequences within an organism’s genome. Unlike traditional breeding or random mutagenesis, gene editing enables precise gene knockout, insertion, or sequence replacement at defined genomic locations. This precision allows researchers to directly investigate gene function and accelerate biological discovery.
With the emergence of CRISPR/Cas systems, gene editing has become faster, more efficient, and widely accessible, transforming plant biotechnology and molecular biology research.
Principle of CRISPR-Based Gene Editing
CRISPR gene editing relies on a programmable guide RNA (gRNA) that directs a Cas nuclease to a specific genomic target. Once bound, the nuclease introduces a double-strand DNA break. The cell repairs this break through natural repair pathways such as non-homologous end joining (NHEJ) or homology-directed repair (HDR).
These repair processes generate targeted mutations or precise sequence insertions, enabling accurate genome engineering for functional studies and trait improvement.
