Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R). Assertion (A): The nematode cannot survive in a transgenic host which expresses specific interfering RNA. Reason (R): Nematode-specific gene introduced in the host produces both sense and antisense complementary RNA which initiate RNA interference in the host cell. In light of the above statement, choose the most appropriate answer from the option given below :
Which of the following is not an application of PCR (Polymerase Chain Reaction)?
