Another term used for mobile genetic elements which may be used as a source of complementary RNA in RNA inter- ference technique is:

Options

A. phage DNA
B. transposon
C. jumping gene
D. both (2) and (3)

Answer

To solve the question about the term used for mobile genetic elements that may serve as a source of complementary RNA in RNA interference techniques, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Mobile Genetic Elements**:
- Mobile genetic elements are segments of DNA that can move around within the genome. They are crucial in genetic variation and can influence gene expression.

2. **Identify the Role of Complementary RNA in RNA Interference**:
- RNA interference (RNAi) is a biological process where RNA molecules inhibit gene expression or translation. Complementary RNA is essential in this process as it binds to specific mRNA to silence it.

3. **Recognize Types of Mobile Genetic Elements**:
- The question mentions terms like "Fudge DNA," "Transposome," and "Jumping Gene." Among these, we need to identify which one is commonly associated with RNA interference.

4. **Relate Mobile Genetic Elements to RNA Interference**:
- Transposons are a type of mobile genetic element that can replicate through RNA intermediates. They can produce double-stranded RNA, which is crucial for the RNA interference mechanism.

5. **Select the Correct Answer**:
- From the options provided, "Transposome" is the term that aligns with mobile genetic elements involved in RNA interference. Therefore, the answer is **Transposome**.

### Final Answer:
The term used for mobile genetic elements that may be used as a source of complementary RNA in RNA interference techniques is **Transposome**.
