Why Gene Therapy Is Good ?  Why Gene Therapy Is Good ?  Gene
therapy involves technique of replacing absent or defective gene
by a corrective gene, so that the body can make the correct
enzyme or protein and consequently eradicate the root cause of
genetic disease.  A gene can be defined as an area of DNA that
controls genetic characteristics of a person. Genes contains the
information to build and maintain their cells and pass genetic
attributes to offspring. Genes also determine person’s sex,
physical trait and IQ. Scientists believe that every individual
has about 25,000 genes per cell. A genetic mutation, or
alteration, in any one of these genes can result in hereditary
disease, physical impairment, or shortened life span. This
genetic mutation can be passed on from one generation to
another. By gene therapy one can eliminate these changes by
replacing faulty gene by genetically engineered gene.  Gene
therapy also holds promise for people with HIV-AIDS, cancer,
muscular dystrophies, hemophilia A, and cert
