Match List I with List II : List I List II A PCR I Cellular defense in all eukaryotic organisms B -1 antitrypsin II Detection of mutated genes in suspected cancer patients C RNAi III Single stranded DNA or RNA tagged with a radioactive molecule D Probe IV Used to treat emphysema Choose the correct answer from the options given below:

Options

  1. AA-II, B-I, C-IV, D-III
  2. BA-III, B-IV, C-I, D-II
  3. CA-II, B-IV, C-I, D-III
  4. DA-IV, B-II, C-III, D-I

Correct answer

C. A-II, B-IV, C-I, D-III

Step-by-step solution

PCR (Polymerase Chain Reaction) is routinely used to detect mutations in genes in suspected cancer patients. -1 antitrypsin is a biological product produced by transgenic animals, which is used to treat emphysema. RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defense. A probe is a single-stranded DNA or RNA tagged with a radioactive molecule, used to detect complementary sequences by hybridization. Therefore, the correct matching is A-II, B-IV, C-I, D-III. Answer: A-II, B-I
