The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Myocardial Infarction**: - Myocardial infarction, commonly known as a heart attack, occurs when a part of the heart muscle dies due to a lack of oxygen. This lack of oxygen is often caused by a blockage in the coronary arteries, which supply blood to the heart. 2. **Role of Thrombus**: - The blockage in the coronary arteries is typically due to a thrombus (a blood clot). When a thrombus forms, it obstructs blood flow, preventing oxygen from reaching the heart tissue, leading to its death. 3. **Introduction of Streptokinase**: - Streptokinase is an enzyme produced by the bacterium Streptococcus. It has the ability to dissolve blood clots, making it a valuable therapeutic agent in treating myocardial infarction. 4. **Genetic Engineering and Recombinant DNA Technology (RDT)**: - Genetic engineering techniques, specifically recombinant DNA technology, have been employed to modify the production of streptokinase. This modification enhances its efficacy and safety for medical use. 5. **Application in Treatment**: - The modified streptokinase is administered to patients experiencing a myocardial infarction. It acts as a "clot buster," dissolving the thrombus and restoring blood flow to the affected part of the heart. 6. **Conclusion**: - Both the assertion (A) that myocardial infarction can be treated more effectively due to genetic engineering and the reason (R) that streptokinase modified by RDT is used as a clot buster are correct. The reason provided explains the assertion accurately. ### Final Answer: Both the assertion and reason statements are correct, and the reason is the correct explanation for the assertion. ---
