The cloning vectors M13 has genetic material

Options

A. (a) ssRNA
B. (b) dsRNA
C. (c) ssDNA
D. (d) dsDNA

Answer

### Step-by-Step Solution:

1. **Identify the Cloning Vector**: The question asks about the genetic material present in the cloning vector M13. M13 is known to be a bacteriophage.

2. **Understand the Nature of M13**: M13 is a type of virus that specifically infects bacteria. This characteristic is important as it defines its role in recombinant DNA technology.

3. **Recognize the Application**: M13 is extensively used in recombinant DNA technology as a cloning vector. Cloning vectors are tools that allow for the transfer of genetic material into host organisms.

4. **Evaluate the Characteristics of M13**: M13 is favored as a cloning vector due to its small size and high cloning capacity. These features make it efficient for genetic engineering applications.

5. **Determine the Type of Genetic Material**: Upon examining the structure of M13, it is revealed that its genetic material is single-stranded DNA (ssDNA). This is a crucial detail as it distinguishes M13 from other types of cloning vectors that may contain double-stranded DNA.

6. **Select the Correct Answer**: Given the information, the correct answer to the question about the type of genetic material present in M13 is **single-stranded DNA**.

### Final Answer:
The genetic material present in the cloning vector M13 is **single-stranded DNA**.
