WebGene knockdown is temporary and often incomplete, unlike gene knockout, which is permanent and complete. In research laboratories, genes have traditionally been knocked down using small interfering RNA (siRNA) or short hairpin RNA (shRNA). WebGene knockout disrupts the DNA to prevent expression of a gene. CRISPR knockout commonly results from NHEJ (non-homologous end joining) of double-strand breaks. ...
