From Wikipedia, the free encyclopedia. A gene knockout (abbreviation: KO) is a genetic technique in which one of an organism 's genes is made inoperative (knocked out of the organism). knockout mouse (left) that is a model of obesity, compared with a normal mouse. A conditional knockout allows gene deletion in a tissue or time specific manner. This is done by introducing short sequences called loxP sites around the gene.
CRISPR/Cas9, a gene-editing technique that can target and modify DNA with groundbreaking accuracy, is both the newest darling and the newest villain of genetics research.Invented in 2012 by scientists at the University of California, Berkeley, CRISPR/Cas9 has received a lot of attention this year.f scientists are able to nail down the use of CRISPR/Cas9 in human germ cells, thereâs no question that it could confer major benefits. Namely, the technology could eradicate hereditary diseases such as cystic fibrosis, sickle-cell anemia, and Huntingtonâs disease from a family line altogether.
