Question 17 17.

Which of the following experiments uses a selectable marker?

I. An experiment in which genetically modified bacteria are blue and all other bacteria are white.

II. An experiment in which the bacteria that has been genetically modified to produce the human insulin protein is identified by checking the DNA sequence.

III. A fruit fly experiment in which a lethal gene kills all progeny except those of the desired genetic makeup.

Question 18 18. Which of the following statements is NOT true?

Question 19 19. Which of these is NOT a step in the process of using a microarray to determine gene expression?

Question 24 24. A scientist isolates a human DNA repair gene and inserts it into a plasmid. The plasmid is inserted into a bacterial cell, so more plasmid can be produced. After isolating the plasmid from the bacterial cells, the scientist inserts the plasmid DNA into a human tissue culture cell using a virus. Which of the following statements regarding HOSTS is TRUE?

Question 25 25. Why is Taq polymerase used in PCR reactions instead of human polymerase?
