What is Gene Therapy?

How can we answer this conflicting question?

Gene Therapy

Gene Therapy could be a way to fix a genetic problem at its core. By adding a corrected copy of a defective gene, gene therapy promises to help diseased tissues and organs work properly. This treatment is different from traditional drug-based treatment, which may treat symptoms but not the genetic problems.

Fixing Gene Therapy.

Sometimes when a gene is defective, no functional protein is being made from it. In cases like these, adding a functional copy of the gene could correct the problem. But sometimes a defective gene codes for a protein that starts doing something it shouldn't or prevents another protein from doing its job. In order to correct the problem, you would need to get rid of the misbehaving protein.
