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 inserts genetic material into a host genome, genome editing targets the insertions to site-specific locations.
Gene editing is one possible tool in the laying hen breeding industry to provide an alternative to Chick culling. With this technology, breeding hens are given a genetic marker that is only passed down to male offspring. These males can then be identified during incubation and removed from the egg supply, so that only females hatch.
CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / (crisper), refers to a clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.
The added gene may itself be modified to make it express more efficiently. This vector is then inserted into the host organism's genome. For animals, the gene is typically inserted into embryonic stem cells, while in plants it can be inserted into any tissue that can be cultured into a fully developed plant.
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.

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. Examples of gene editing are CRISPR, zinc finger nuclease, transcription activator-like effector nuclease (TALEN), oligonucleotide directed ...
A UK law allowing gene-edited food has been paused and some British scientists fear being overtaken. Its supporters dream of heat-resistant cows. But gene editing is making others nervous
