Using CRISPR to disable genes: CRISPR gene editing can disable genes by causing errors during DNA rejoining, leading to clinical and agricultural applications
CRISPR gene editing technology allows scientists to cut specific genes and, due to the error-prone nature of DNA rejoining, often results in the deletion or addition of a few letters, which can disable the gene. This "gene knockout" technique has proven clinically useful, as seen in the elimination of genes that make humans susceptible to HIV or those that prevent the production of healthy hemoglobin in sickle cell disease. This technology also has applications in agriculture. While the genetic code is read as a continuous string, losing just a letter or two can render the text gibberish, a phenomenon known as a frame shift. By cutting a gene and allowing nature to rejoin it imperfectly, researchers can effectively disable it, opening up possibilities for treating diseases and improving crops.
Manipulating DNA repair for gene editing: Gene editing uses natural DNA repair process to make precise changes to DNA sequences, opening possibilities for curing genetic diseases and creating gene-edited organisms
The natural process of DNA repair in cells can be manipulated for gene editing through techniques like gene knockout and gene repair using identical DNA templates.
