Human gene editing involves changing of the genes by adding, removing or replacing pairs of DNA. It offers a significant potential to advice on therapeutic and fundamental science application. The gene editing is applied to gremlin cells, tissues embryo and human cells. This helps in improvement of normal biology-human thinking which involves more knowledge of human fertility, development, and reproduction. It also gives an understanding of various diseases and how to treat them. Genome editing is used in clinics to test and treat genetic disease. Genome editing involves the use of enzyme known as engineered nuclease which is used to cut the genome in a particular place. The engineered nuclease comprises of two parts that are the put which cuts the DNA and the part of the DNA that guides the nuclease (Kim, Kim, Cho, Kim, & Kim, 2014).
Human gene editing is done by cutting and pasting specialized proteins of DNA. The proteins are in three categories, TALENs, Zones, and CRISPRs. CRISPRs refer to Cas9 which consist of enzymes and genetic that is used to edit the DNA, for the virus to work, the machine is used to take over the cells until those cells burst. In cases where the genetic bacteria evolve, DNA waves are cut then the proteins are chopped. Many times the bacteria may survive the cutting; in this case, tiny snippets of DNA are incorporated. For the memory of genetic be kept on its palace, RNA is used. In the nucleus, the Crips-Cas9 is used to bump the genome. It also needs to grab itself into DNA. This makes the RNA to see it is matched with the DNA.
In human gene editing, only one gene is used when carrying out gene by gene basis. Technology such as mass spectrometry, expression, and gene microarrays are used .those innovative technology address and unravel disease. Technological improvement makes the expression of the genome to be easier. Microarrays are different microscopic of DNA spots which are attached on a solid surface. Microarrays also provide different genotypes and allocated chromosomal which are associated with a certain disease. The biological principles associated with the human gene-editing are respect for the person, transparency, science responsibility, well-being and due care (Hendel, Bak, Clark, Kennedy, Ryan, Roy, & Bacchetta, 2015).
