The evolution of gene editing and DNA repair, using the various vectors to modify the target DNA.

Genome Editing, also known as gene editing, is a group of technologies under genetic engineering that gives scientists the ability to change an organism’s DNA. This group of technologies enable genetic material to be added, removed, or altered at particular locations in the genome. Several methods of implementing foreign DNA into an organism's existing genome have been utilized in the past, however, the most recent is called Crispr-Cas9. Short for clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9, the Crispr-Cas9 system has generated a lot of excitement among the scientific community as it has been the fastest, cheapest, most accurate and efficient means of altering DNA compared to its predecessors. Genome editing is of great interest in the prevention and treatment of human diseases. Currently, most research on genome editing is done to understand diseases using cells and animal models. Scientists are still working to determine whether this approach is safe and effective for use in people. It is being explored in research on a wide variety of diseases, including single-gene disorders such as cystic fibrosis, hemophilia, and sickle cell disease. It also holds promise for the treatment and prevention of more complex diseases, such as cancer, heart disease, mental illness, and human immunodeficiency virus (HIV) infection. [1]

History

The idea of using gene editing to treat disease or alter traits is not a novel one and dates back to at least the 1950s and the discovery of the double-helix structure of DNA. In the mid 20th century, researchers realized that small changes in the DNA sequence could mean the difference between health and disease. This understanding led to the theory that by identifying “molecular mistakes” that cause genetic diseases we could fix those mistakes, enabling the prevention or reversal of these diseases. This concept was the underlying idea behind gene therapy through genome editing, and was seen as the future of molecular genetics. [2]
