Gene editing is a form of genetic engineering by which DNA is substituted, altered, inserted or modified in an organism’s genome. During this process, genetic variants are introduced through DNA sequence alterations that potentially affect the function of the genes in producing the traits desired by the designer. These modifications can introduce insertion, deletion or rearrangement mutations that together lead to novel and beneficial traits of the target organism. These traits can then be used for one’s advantage in improving the quality of life or to simply improve the way the individual looks and behaves. Sometimes these results can be desirable both to the target organism and to the researcher who conducted the study. click reference for more info.
The procedure of gene editing is carried out through mutagenesis, a process that involves the introduction of an insertional mutation into the host cell through error, natural selection, or radiation. This insertion results in the formation of a new strand of DNA which can be inserted into the target cell to cause further mutations. These mutations accumulate over time as parts of the existing DNA sequence become transcribed into the target organism’s transcription units. This further adds to the genetic makeup of the subject by introducing novel traits or changes.
This form of genetic innovation is done with the help of sophisticated technologies and advanced methodologies that allow precise control over the results. It is estimated that nearly 20% of all cells in the body carry DNA, which determines their existence and structure. Most of these DNA variations have a role to play in creating the basic structure of an organism, including development, growth, and maintenance. Hence, editing the genes can be used not only to address lifestyle issues such as disease, but can also be used to create a more ideal environment for future generations. Gene therapy research has the potential to offer individuals with diseases a chance for recovery from life-threatening diseases by means of correcting their genetic weaknesses. Some of the recent studies on this topic have resulted in the establishment of what are known as ‘genic rescue’ strategies, which use gene editing to attempt to improve the general health and wellness of a patient.
