Question

Recombinant DNA technology has many medical applications. Which of the following has not yet been attempted or achieved?

Options

• Genetic testing for carriers of harmful alleles

• Prenatal identification of genetic disease genes

• Introduction of genetically engineered genes into human germ cells

• Production of hormones for treating diabetes and dwarfism

Answer 1

Introduction of genetically engineered genes into human germ cells

Explanation:

Recombinant DNA technology has achieved genetic testing for harmful alleles, prenatal identification of genetic disease genes, and production of hormones like insulin for diabetes and dwarfism treatment. However, introducing genetically engineered genes directly into human germ cells has not yet been attempted or achieved due to ethical and technical challenges.
