Vector which can be used for both prokaryotes as well as eukaryotes is known as:

Options

A. Shuttle vector
B. Cosmid vector
C. Plasmid
D. Eco IM

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a type of vector that can be utilized in both prokaryotic and eukaryotic organisms.

2. **Defining Vectors**: Vectors are DNA molecules used to carry foreign genetic material into another cell. They are essential tools in biotechnology for gene cloning and expression.

3. **Types of Vectors**:
- **Shuttle Vectors**: These are designed to replicate in two different host species, typically one prokaryotic (like bacteria) and one eukaryotic (like yeast or mammalian cells). This allows for the manipulation and testing of foreign DNA in various cellular environments.
- **Cosmid Vectors**: These are hybrids of plasmid and phage vectors, primarily used in prokaryotes.
- **Plasmid Vectors**: These are circular DNA molecules that can replicate independently in prokaryotic cells but are not typically used in eukaryotic cells.
- **E. coli I.M.**: This refers to a specific strain of bacteria and is not a type of vector.

4. **Identifying the Correct Answer**: Among the options provided, the only vector that can function in both prokaryotes and eukaryotes is the **Shuttle Vector**.

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