George palade observed granular structure under electron microscopy which is composed of

Options

A. RNA & DNA
B. RNA & Carbohydrates
C. RNA & Proteins
D. RNA & Amino acids

Answer

To solve the question about what George Palade observed under electron microscopy, we can follow these steps:

### Step 1: Identify the Structure
- George Palade observed a granular structure under electron microscopy. This structure is known as ribosomes.

**Hint:** Think about the key discoveries made by George Palade and what structures are commonly associated with him.

### Step 2: Understand Ribosomes
- Ribosomes are dense particles that play a crucial role in protein synthesis. They are composed of two main components.

**Hint:** Recall what ribosomes do and what they are made of.

### Step 3: Components of Ribosomes
- The two main components of ribosomes are ribonucleic acid (RNA) and proteins. They do not contain DNA or carbohydrates.

**Hint:** Consider the types of macromolecules that are involved in the structure of ribosomes.

### Step 4: Eliminate Incorrect Options
- The options provided are:
1. RNA and DNA
2. RNA and Carbohydrates
3. RNA and Proteins
4. RNA and Amino Acids
- Since ribosomes are made of RNA and proteins, we can eliminate the other options.

**Hint:** Focus on the specific components that are known to make up ribosomes.

### Step 5: Conclusion
- The correct answer is that ribosomes are composed of RNA and proteins.

**Final Answer:** The correct option is **RNA and Proteins**.

### Summary of Steps:
1. Identify the structure observed by George Palade (ribosomes).
2. Understand the function and significance of ribosomes.
3. Recognize that ribosomes are composed of RNA and proteins.
4. Eliminate incorrect options based on this knowledge.
5. Conclude with the correct answer.
