Genes are the basic physical and functional
units of
heredity, and gene therapy is a technique for correcting
defective genes responsible for diseases. It works by
inserting a normal gene into the genome (the complete set of genes in a living cell) to replace an
abnormal gene. A carrier
molecule called a vector must be used to deliver the therapeutic gene to the patient's target cells. But there are many limitations.
· The rapidly dividing nature of many
cells means that gene therapy may be
short - lived;
· The normal gene may be atacked and
repelled by the patient's
immune system;
· Gene therapy works best on disorders arising from the
mutation of a single gene.
