The news about viruses isn't all bad. In a technique called gene therapy, scientists take advantage of a virus's ability to enter a host cell. They add genetic material to a virus and then us the virus as a "messenger service" to deliver the genetic material to cells that need it.

Scientists hope to be able to use viruses for gene therapy because viruses can what?
podem mutar
What uses viruses to help people with genetic disorders?
Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes, or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene, restoring the function of the protein. Viruses are used in gene therapy as vectors that are genetically engineered to deliver the new copy of the gene by infecting the cell.
What 'tools' are used in gene therapy?
Viral vectors are the tools used in gene therapy.
How are viruses benificial for humans?
One use for viruses as of late has been gene therapy. Certain retroviruses can be used to splice in engineered genes into patients in the hope of treating genetic disorders.
How could gene therapy be used to treat cancer?
With the help of Gene therapy we can replace or supress the cancer gene
How gene therapy might be used to treat cytic fibrosis?
In cystic fibrosis there is an inherited gene that you have that is causing it, so if gene therapy is used, you can replace the gene with the effected one
How does gene therapy effect children?
Gene therapy effects children by helping to cure disease and to lengthen lives. Gene therapy can also be used to eliminate diseases that are inherited.
What is gene therapy and how is it used?

Inserting working copies of a gene directly into the cells of a person with a genetic disorder is called what?
Gene TherapyGenetic disorders are caused by an abnormality in person's DNA.
Are viruses used in gene therapy to insert DNA into target cells of patient?
Sometimes. Another method used to insert DNA but that does not involve viruses is to use microscopic gold "shotgun pellets" coated with the desired DNA and propelled into the tissue with a pulse of high pressure air.
Why do you need gene therapy?
gene therapy is when a faulty gene is repaired or replaced
