Read the given statements and select the correct option.
Statement 1 : The cloning vector is required to have very few, preferably single, recongnition sites for the commonly used restriction enzymes.
Statement 2: Presence of more than one recongnition sites within a cloning vector will generate several fragments, which will complicate the process of gene cloining.
1) Both statements 1 and 2 are correct
2) statement 1 is correct but statement 2 is incorrect
3) statement 1 is incorrect but statement 2 is correct
4) None of the above

Answer

To solve the question, we need to analyze both statements regarding cloning vectors and their recognition sites for restriction enzymes.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- The statement claims that a cloning vector should have very few, preferably a single, recognition site for commonly used restriction enzymes.
- This is correct because having fewer recognition sites simplifies the cloning process. If there is only one recognition site, the enzyme will cut the vector at that specific site, producing a single fragment that can be easily manipulated.

2. **Understanding Statement 2**:
- This statement asserts that the presence of more than one recognition site within a cloning vector will generate several fragments, complicating the gene cloning process.
- This statement is also correct. If multiple recognition sites are present, the restriction enzyme will cut at each site, resulting in multiple fragments. This can complicate the cloning process as it becomes difficult to isolate the desired fragment.

3. **Conclusion**:
- Since both statements are correct, we can conclude that the correct option is:
- **Option 1: Both statements 1 and 2 are correct.**

### Final Answer:
The correct option is **1) Both statements 1 and 2 are correct.**
