Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): rDNA technology is a two-component system: a compatible host and a vector. Reason (R): The vector provides essential sequences required for its replication in a compatible host which provides various replication functions. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Ensure that both the assertion and its explanation align conceptually.

Answer 1

The Correct Option is A

Step 1: Concept
rDNA technology, vector, host cell

Step 2: Meaning
Understanding the components and roles in rDNA technology.

Step 3: Analysis
Assertion (A) states that rDNA technology requires a compatible host and a vector. Reason (R) explains that vectors provide essential sequences for replication within a compatible host, which implies various replication functions. This aligns with the definition of a vector used in rDNA technology.

Step 4: Conclusion
Both statements are correct. The reason correctly explains why the assertion is true by detailing what a vector does within the context of a host cell in rDNA technology. Final Answer: (A)
