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.
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.
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.
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 is characterised by making small edits to the genome at a specific location, often following cutting of the target DNA region by a site-specific-nuclease such as CRISPR. [12] Genetic modification usually describes the insertion of a transgene (foreign DNA, i.e. a gene from another species) into a random location within the genome.
