Clot buster is obtained from a genetically modified bacterium belonging to the genus

Options

A. Saccharomyces
B. Monascus
C. Trichoderma
D. Streptococcus

Answer

To solve the question regarding the origin of the clot buster obtained from a genetically modified bacterium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the genus of a genetically modified bacterium that produces a substance known as a "clot buster." Clot busters are used to dissolve blood clots in medical treatments.

2. **Identifying Clot Busters**: One of the most commonly known clot busters is streptokinase. This is an enzyme that helps dissolve blood clots and is used in medical treatments for conditions such as heart attacks.

3. **Researching the Source of Streptokinase**: Streptokinase is produced by certain bacteria. To find the specific genus, we need to identify which bacteria produce streptokinase.

4. **Identifying the Bacterium**: Streptokinase is derived from the bacterium belonging to the genus **Streptococcus**. This genus includes various species of bacteria, some of which are known to produce streptokinase.

5. **Confirming Genetic Modification**: The question specifies that the bacterium is genetically modified. Streptococcus bacteria can be genetically engineered to enhance the production of streptokinase for therapeutic use.

6. **Final Answer**: Based on the information gathered, the correct answer to the question is **D. Streptococcus**.

### Final Answer:
**D. Streptococcus**
