Question
Gene therapy attempts to _______________.
- Combine cells taken from different species
- Treat disease by altering a patient's DNA
- Determine a child's sex before birth
- Provide genes to people who have none
Hint:
Gene therapy is a biotechnological process in which the DNA or genetic material is manipulated.
The correct answer is: Treat disease by altering a patient's DNA
So, the correct option is option 2. Because gene therapy attempts to remove the gene (functional segment of DNA) and replacing.
- Gene therapy involves such methods that are used to treat genetic diseases.
- Genetic diseases are inherited from parents and can be passed on to the children of next generation.
- So, the patient may suffer from serious disorders like haemophilia, muscular dystrophy or cystic fibrosis.
- Such diseases are caused by change in the genetic material.
- From the genome of the patient, a single gene or multiple genes can be mutant, missing or nonfunctional.
- So the gene therapy is the only way to cure this.
- The abnormal gene is replaced by a normal gene from the patient's genetic material.
