alleryTreating phenylketonuria (PKU) by correcting the genetic change in liver cells is an example of:
AReproductive cloning
BSomatic cell gene therapy
CArtificial insemination
DBioremediation
Answer & Solution
Correct answer: B. Somatic cell gene therapy
1. PKU arises from a genetic change in hepatocytes (liver cells).
2. Correcting genetic disorders in somatic cells is called somatic cell gene therapy.
3. Reproductive cloning makes whole organisms, artificial insemination is a breeding method, and bioremediation cleans pollutants; none treat a gene defect in body cells.
