Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following tools of recombinant DNA technology is incorrectly paired with its use?
A
DNA polymerase-polymerase chain reaction to amplify sections of DNA
B
reverse transcriptase-production of cDNA from mRNA
C
restriction enzyme-analysis of RFLPs
D
DNA ligase-cutting DNA, creating sticky ends of restriction fragments
Explanation: 

Detailed explanation-1: -Answer and Explanation: The correct answer is (b) DNA ligase cutting DNA, creating sticky ends of restriction fragments.

Detailed explanation-2: -So, the correct option is ‘Introns’.

Detailed explanation-3: -Recombinant DNA technology can be accomplished only if we have the following key tools i.e., reaction enzymes, polymerase enzyme, ligases and vectors.

Detailed explanation-4: -They shorten the DNA by one nucleotide at a time, they do not digest it into fragments. Thus the correct answer is option D.

Detailed explanation-5: -The correct answer is Dolly. Concept: Recombinant DNA technology is the process of combining DNA molecules from two different organisms and inserting them into a host organism to create new genetic combinations.
