Genome editing is a type of genetic engineering that allows scientists to make precise changes in an organism's DNA. This can involve adding, deleting or modifying specific genes within the genome of an organism using various techniques such as CRISPR-Cas9 system. The goal of this process is to alter the traits of an organism, either by removing or silencing certain genes that cause diseases or by introducing new genetic material to enhance desired characteristics. Genome editing has many potential applications in fields like medicine, agriculture and biotechnology, including the development of new treatments for genetic disorders, improving crop yields, and creating new strains of animals with specific traits.
