Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism. Unlike early genetic engineering techniques that randomly insert genetic material into a host genome, genome editing targets the insertions to site-specific locations.
Human germline engineering (HGE) is the process by which the genome of an individual is modified in such a way that the change is heritable. This is achieved by altering the genes of the germ cells , which mature into eggs and sperm.
CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]
In a 2004 paper published in the journal Nature, the International Chicken Genome Sequencing Consortium found that although a chicken doesn't have as much DNA as a human, it has about the same ...
Genome editing uses artificially engineered nucleases that create specific double-stranded breaks at desired locations in the genome. The breaks are subject to cellular DNA repair processes that can be exploited for targeted gene knock-out, correction or insertion at high frequencies.

Gene editing may refer to: . Genetic engineering of any organism by genome editing. Gene editing is the emerging molecular biology technique which makes very specific targeted changes by insertion, deletion or substitution of genetic material in an organism's DNA to obtain desired results.
In 2009, the first human biological drug produced from such an animal, a goat, was approved. The drug, ATryn, is an anticoagulant which reduces the probability of blood clots during surgery or childbirth was extracted from the goat's milk. [42] Human alpha-1-antitrypsin is another protein that is used in treating humans with this deficiency. [43]
