Understanding Genetic Medicine Statements

This question requires evaluating the accuracy of three statements related to genetic medicine, a field focused on treating diseases by modifying a patient's genes.

Statement Analysis

• Statement 1: Genetic medicines correct/compensate for the faulty genes responsible for disease.

  This statement is correct. The fundamental principle of genetic medicine, particularly gene therapy, is to address the root cause of genetic disorders by repairing, replacing, or inactivating faulty genes, or providing a functional copy of the gene.

• Statement 2: Engineered viruses and lipid nanoparticles are used as carriers of the genetic medicine.

  This statement is correct. Gene therapy requires vectors to deliver the therapeutic genetic material into target cells. Modified viruses (viral vectors) and non-viral methods like lipid nanoparticles (LNPs) are common delivery vehicles used in genetic medicine.

• Statement 3: Genetic medicines alter the entire DNA sequence.

  This statement is incorrect. While gene editing technologies can precisely alter DNA, genetic medicine typically aims to target specific faulty genes causing a disease. Altering the entire DNA sequence is not the standard objective and could lead to unintended, widespread genetic changes.

Conclusion on Correct Statements

Based on the analysis, statements 1 and 2 accurately describe key aspects of genetic medicine, while statement 3 is an overgeneralization and generally incorrect.

Selecting the Correct Option

Therefore, the correct option includes only statements 1 and 2.

Option 3: 1 and 2 only correctly identifies the accurate statements.
