Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Patients who have undergone myocardial infarction are often treated with Streptokinase. Reason (R): Streptokinase is produced by the bacterium Streptococcus and acts as a 'clot buster' to remove clots from the blood vessels. In the light of the above statements, choose the most appropriate answer f
Options
- ABoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
- BAssertion (A) is true but Reason (R) is false.
- CBoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- DAssertion (A) is false but Reason (R) is true.
Correct answer
C. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Step-by-step solution
Myocardial infarction (heart attack) is typically caused by a blood clot in the coronary arteries. Streptokinase, produced by the bacterium Streptococcus and modified by genetic engineering, is used clinically as a 'clot buster'. It helps in dissolving the clots in the blood vessels, thereby restoring blood flow. Therefore, both the Assertion and Reason are true, and the Reason correctly explains why patients with myocardial infarction are treated with Streptokinase. Answer: Both Assertion (A) and Reason (R) are tr
