Answer:

The correct answer would be  

  • It cures all cases of cystic fibrosis.
  • It involves the modification of DNA.
  • It attempts to replace a mutated gene with normal DNA.
  • It does not always cure patients who use it.

Gene therapy is an experimental technique used to treat the genetic disorder by transplanting the normal gene into the cell in order to replace the missing or defective gene in a cell.

It helps in treating genetic disorders such as cystic fibrosis, hemophilia et cetera.

It can be of two types of somatic gene therapy and germline gene therapy.

Answer:

Gene therapy  can be described as an important application of biotechnology that is used to introduce normal genes into the cell, which possess defective or missing gene. It is significant in treating genetic disorders ( for instance, it cures cystic fibrosis by introducing normal gene for CFTR protein). This means that DNA with defective gene is modified or replaced with a normal DNA segment ( gene).

But it does not always cure the patients who use it ( for instance,   inserted gene may be recognized as foreign by immune system of the patient, which destroys the inserted gene).

Thus, the correct answers are-

It cures all cases of cystic fibrosis.

It involves the modification of DNA.

It attempts to replace a mutated gene with normal DNA.

It does not always cure patients who use it.
