The 'clot buster ' produced by Streptococcus and modified by genetic engineering is

Options

A. Streptokinase
B. Penicillin
C. Cyclosporin A
D. Statins

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the name of the 'clot buster' produced by Streptococcus and modified through genetic engineering.

2. **Identifying the Clot Buster:**
The primary 'clot buster' produced by the bacterium Streptococcus is known as **streptokinase**. This enzyme is crucial in medical applications for dissolving blood clots.

3. **Role of Streptokinase:**
Streptokinase is an enzyme that activates plasminogen, leading to the conversion of plasminogen into plasmin, which then breaks down fibrin in blood clots. This process is known as fibrinolysis.

4. **Genetic Engineering Modification:**
Streptokinase can be genetically engineered to enhance its effectiveness or to produce it in larger quantities. This modification allows for its use in treating conditions like myocardial infarction (heart attack) by clearing clots in the blood vessels.

5. **Conclusion:**
Therefore, the correct answer to the question is **streptokinase**.

**Final Answer:**
The 'clot buster' produced by Streptococcus and modified by genetic engineering is **streptokinase**.
