https://globletime.com/technology/look-wellsaid-vocalid-aihao-mit-technologyreview/ Gene editing technology is a set of techniques used to make precise changes to the DNA (genetic material) of living organisms. It involves the use of molecular tools to target and modify specific genes in a genome, to alter the organism’s traits or functions.
There are different types of gene editing technologies, but one of the most widely used is the CRISPR-Cas system. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are DNA sequences that are repeated in the genome of bacteria and other organisms. Cas refers to the Cas9 protein, an enzyme that can cut DNA at specific locations within the genome.
The CRISPR-Cas system works by using a small RNA molecule to guide the Cas9 protein to a specific location on the genome where it can cut. Once the DNA is cut, the cell’s repair mechanisms can be harnessed to make specific changes to the DNA sequence.
Gene editing technologies have a wide range of potential applications in medicine, agriculture, and industry. For example, they could be used to correct genetic mutations that cause diseases, improve the productivity and nutritional value of crops, or create new materials and chemicals.
