Genome editing refers to the technique used to modify an organism's genetic material at specific locations in the genome. Techniques such as CRISPR-Cas9 enable precise alterations, including additions, deletions, or substitutions of DNA sequences. Genome editing has vast applications, including developing genetically modified organisms (GMOs), advancing medical research, and potentially curing genetic diseases. This technology raises ethical considerations about its use, particularly in humans, and underscores the importance of responsible scientific stewardship in genetic research.
