Question

Diseases that are caused by the malfunction of a phototropic gene are:

• A. Cured by dietary restrictions
• B. Reversible by gene therapy
• C. Called as syndromes
• D. Extremely rare

Answer 1

The correct option is B Reversible by gene therapy

Phototropism is the growth of an organism which responds to a light stimulus. It is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient's cells instead of using drugs or surgery.

So the correct option is 'Reversible by gene therapy'.
