Which of the following statements with regard to genetic medicine is/are correct?1.Genetic medicines correct/compensate for the faulty genes responsible for disease.2.Engineered viruses and lipid nanoparticles are used as carriers of the genetic medicine.3.Genetic medicines alter the entire DNA sequence. Select the answer using the code given below:

(a) This option claims only statement 1 is correct. While statement 1 is correct, statement 2 is also correct as lipid nanoparticles and engineered viruses are standard delivery vectors for genetic therapies, making this option incomplete.

Summary. (b) This option includes statement 3, which claims genetic medicines alter the entire DNA sequence. Statement 3 is incorrect because genetic medicines target specific faulty genes or RNA sequences rather than altering the entire organism's DNA sequence indiscriminately. (c) Official key: 1 and 2 only. Statement 1 is correct because genetic medicines aim to correct, replace, or compensate for faulty genes responsible for hereditary or acquired diseases. Statement 2 is correct because safe delivery into target cells requires specialized vectors like engineered viruses (e.g., adeno-associated viruses) or lipid nanoparticles. (d) This option includes all three statements. It is incorrect because statement 3 is factually wrong; genetic treatments do not alter the entire DNA sequence of an individual. Summary. Official key is (c). Genetic medicines specifically target and correct faulty genes or regulate protein expression using precise molecular interventions rather than rewriting an entire genome, and they rely on advanced delivery mechanisms like lipid nanoparticles and engineered viruses.
