A tumour inducing Ti plasmid of Agrobacterium tumefaciens has been modified into a cloning vector which is not pathogenic to the plants, However, it is still able to use its mechanism to deliver genes of our interest into various plants.
Read the given statements and select the correct option.Statement 1: T...
Understanding the Statements
The question presents two statements about the Ti plasmid, a well-known tool in genetic engineering.
Statement 1: Ti Plasmid as a Cloning Vector
- The Ti plasmid, derived from the bacterium Agrobacterium tumefaciens, is indeed utilized as a cloning vector.
- It facilitates the introduction of foreign genes into plant cells, making it a vital tool in plant biotechnology.
Statement 2: Pathogenic Nature of Ti Plasmid
- Although the Ti plasmid is effective for gene delivery, it is inherently pathogenic.
- The plasmid originally causes crown gall disease in plants, which is a major reason for its pathogenic nature.
Evaluating the Correctness of the Statements
- Statement 1 is correct because the Ti plasmid is widely used in recombinant DNA technology for gene transfer.
- Statement 2 is also correct as the Ti plasmid carries genes that make it pathogenic.
Relationship Between the Statements
- While both statements are correct, Statement 2 does not provide a direct explanation for Statement 1.
- The fact that the Ti plasmid is pathogenic is relevant but does not explain its role as a cloning vector.
Conclusion
- Therefore, the correct answer is option 'C': "Statement 1 is correct and statement 2 is incorrect."
- The misunderstanding arises from interpreting the relationship between the two statements rather than their individual correctness.
In summary, the Ti plasmid serves as an effective cloning vector in genetic engineering, despite its pathogenic properties.
