Why Gene Therapy Is Important. Genes that are flawed and do not work properly can cause disease. Gene therapy is a technique for correcting defective genes responsible for disease development. Researchers may use one of several approaches for correcting faulty genes: 1  A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. This approach is most common. 2  An abnormal gene could be swapped for a normal gene through homologous recombination. The abnormal gene could be repaired through selective reverse mutation, which returns the gene to its normal function. The regulation (the degree to which a gene is turned on or off) of a particular gene could be altered.
Image Credit: Main Image: Gene Amplification, also known as gene duplication or chromosomal duplication, is a cellular process in which multiple copies of a gene are produced. The result is an amplification of the phenotype, or expressed trait, associated with the gene.ot all gene amplification has great importance to evolution. Sometimes, the amplified trait dies with the single organism that experiences the gene duplication. This happens when a gene is over expressed and the trait it codes for is expressed to a level that is unhealthy to the organism.
