Gene editing technologies

Definition

Gene editing technologies refer to advanced methods used to alter the genetic material of organisms in a precise and controlled manner. These technologies enable scientists to add, remove, or modify DNA sequences, leading to significant implications for medicine, agriculture, and biotechnology. With the potential to treat genetic disorders and enhance food security, gene editing raises important ethical and regulatory questions in the healthcare landscape.
