Engineered viruses and lipid nanoparticles are used as carriers of the genetic medicine.<br/>3. Genetic medicines alter the entire DNA sequence.<br/><br/>Select the answer using the code given below :<br/>
Answer
1 and 2 only
1 is correct because genetic medicines/gene therapy aim to replace, inactivate, repair, or otherwise compensate for faulty genes causing disease. 2 is also correct because delivery can use engineered viral vectors and non-viral carriers such as nanoparticles, including lipid nanoparticles. 3 is incorrect because these therapies target specific genes, gene expression, or selected DNA sequences; they do not alter the entire DNA sequence.
