attentions, it is the proteins that perform most life
functions. When genes are altered, encoded proteins are
unable to carry out their normal functions, resulting in
genetic disorders.Gene therapy is the insertion of genes
into an individual’s cells and tissues to treat a disease and
hereditary diseases in which a defective mutant allele is
replaced with a functional one. Gene therapy, is offering
new and exciting possibilities for curing and treating several
genetic disorders.
