The type of ribosomes found in the cytoplasm of the organism responsible for causing typhoid and sleeping sickness are ______ and ______respectivley

Options

A. 70S and 70S
B. 70S and 80S
C. 80S and 70S
D. 80S and 80S

Answer

To solve the question regarding the types of ribosomes found in the cytoplasm of the organisms responsible for causing typhoid and sleeping sickness, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Typhoid is caused by the bacterium **Salmonella typhi**.
- Sleeping sickness is caused by the protozoan **Trypanosoma**.

2. **Understand Ribosome Types**:
- Ribosomes are cellular structures responsible for protein synthesis and are classified based on their size, measured in Svedberg units (S).
- **Prokaryotic Ribosomes**: These are typically **70S** ribosomes, which consist of a small subunit (30S) and a large subunit (50S).
- **Eukaryotic Ribosomes**: These are typically **80S** ribosomes, which consist of a small subunit (40S) and a large subunit (60S).

3. **Determine the Ribosome Type for Each Organism**:
- For **Salmonella typhi** (the bacterium causing typhoid), it has **70S ribosomes**.
- For **Trypanosoma** (the protozoan causing sleeping sickness), it has **80S ribosomes**.

4. **Fill in the Blanks**:
- Based on the information gathered, the types of ribosomes found in the cytoplasm of the organisms responsible for causing typhoid and sleeping sickness are **70S** and **80S**, respectively.

### Final Answer:
The type of ribosomes found in the cytoplasm of the organism responsible for causing typhoid and sleeping sickness are **70S** and **80S**, respectively.
