Answer:
Gene Therapy
Step-by-step explanation:
Gene therapy is an attempt to correct a genetic disorder by replacing a mutated gene with a normal allele.
Gene therapy introduces a normal copy of the gene to restore the function of the protein if a mutated gene causes a necessary protein to be faulty or missing.
Gene therapy is a process in which a new, correct version of the cystic fibrosis transmembrane conductance regulator gene would be placed into the cells in a person's body.
