Assertion (A): In molecular diagnosis, single-stranded DNA or RNA tagged with radioactive molecule is called a probe. Reason (R): A probe always searches and hybridizes with its complementary DNA in a clone of cells.
Show Hint
Probes are key tools in molecular diagnostics for identifying specific genetic sequences.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Show Solution
The Correct Option isA
Solution and Explanation
In molecular diagnostics, a probe is a labeled DNA or RNA strand that identifies specific sequences. It binds to its complementary DNA, indicating that Reason (R) explains Assertion (A).
