Which of the following tools of dna technology is not correctly paired with its use? group of answer choices a. electrophoresis – separation of dna fragments b. dna-ligase – cutting dna, creating sticky ends of restriction fragments c. dna polymerase - polymerase chain reaction to amplify sections of dna d. reverse transcriptase - production of cdna from mrna

The correct answer is B.

Explanation:

According to it's definition, electrophoresis is the technique which is used to get discrete fragments of DNA or RNA through a process of chemical and electrical reactions.

DNA-Polymerase is an enzyme that is used in processes such as replication of the DNA so which is a part of the polymerase chain reaction that is used to make copies of DNA's.

Reverse Transcriptase's definition is exactly as the given one which is to use the enzyme to form new Complementary DNA (cDNA) from RNA templates.

The B option is wrong. DNA-Ligase is an enzyme that joins the DNA strands together, not cutting them.

I hope this answer helps.
