Gene therapy

Gene therapy is the insertion of genes into an individual's cell and biological tissues to treat disease, such as cancer where deleterious mutant alleles are replaced with functional ones.It is an experimental technique that uses genes to treat or prevent disease.In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery.
There are many advantages of gene therapy like tt can cure the humanbeings who have genetic disorders.This is the main advantage of gene therapy in human life.
There are two types of gene therapy:
1) Germ line gene therapy
2) Somatic gene therapy
In germline gene therapy germ cells, i.e., sperm or eggs, are modified by the introduction of functional genes, which are ordinarily integrated into their genomes.
In SOmatic gene therapy the therapeutic genes are transferred into the somatic cells of a patient.
