Gene therapy is the technique of genetic engineering to replace a faulty gene by a normal healthy functional gene. It is a way of treating genetic disease by introducing a piece of $\text{DNA}$ into the cells of an affected individual. Liposomes can be used for gene therapy as they target the cells affected by a genetic disease.
  1. A patient suffers from adenosine deaminase $\text{(ADA)}$ deficiency, an autosomal recessive immune deficiency in which bone marrow lymphoblasts cannot replicate to generate immuno-competent lymphocytes. The treatment option that would cure the patient is:
  1. Germ-line gene therapy to replace one $\text{ADA}$ gene copy.
  2. Germ-line gene therapy to replace both $\text{ADA}$ gene copies.
  3. Somatic cell gene therapy to replace both $\text{ADA}$ gene copies in circulating lymphocytes.
  4. Somatic cell gene therapy to replace one $\text{ADA}$ gene copy in bone marrow lymphoblasts.
  1. Which type of gene therapy is least effective in transferring $\text{DNA}$ to the nucleus?
  1. Adenoviruses.
  2. $\text{DNA}$ attached to a ligand.
  3. Liposomes.
  4. Retroviruses.
  1. Liposomes can be used for gene therapy as they target the cells affected by a genetic disease. The diagram shows the structure of a liposome.
