12. True Reason: The GFP gene encodes GFP protein that is used as a reporter of gene expression. B. 1) The correct answer is c.Helicase Reason: All options are required for PCR except helicase. 2) The correct answer is e.None of the above ( all of the statements are true) Reason: Complementary base pairing is a part of all the above mentioned processes. 3)The correct answer is b.contains a segment of DNA from a foreign source. Reason:Recombinant DNA is formed by process of genetic recombination from DNA of multiple sources. 4)The correct answer is e.All of the above. Reason:All of the above processes define cloniing. 5)The correct answer is d. Western Blot(transference of proteins onto nitrocellulose paper/membrane) Reason: DNA fingerprinting does not involve proteins . Solution 12.
