Final answer:
Gene editing is used in gene therapy to modify or correct genes associated with genetic disorders. Germline editing modifies genes in reproductive cells for future generations, while somatic editing modifies non-reproductive cells for the individual. Examples include editing immune cells for cancer treatment and correcting genetic mutations in liver cells.
Step-by-step explanation:
Gene editing is used for gene therapy by allowing scientists to modify or correct genes that are associated with genetic disorders. It involves making specific changes to the DNA sequence in order to treat or prevent disease.
An example of germline editing is the modification of genes in reproductive cells, such as eggs or sperm, which can be passed on to future generations. Somatic editing, on the other hand, involves modifying genes in non-reproductive cells of the body, such as skin cells or blood cells, which do not affect future generations.
Some examples of somatic editing include the use of CRISPR/Cas9 technology to edit immune cells for cancer treatment, or to correct genetic mutations in liver cells for the treatment of genetic liver disorders.
