Question 11

Imagine that it is 1965 and the bacterium Thermus aquaticus has not yet been discovered. As a geneticist interested in forensics applications, you are attempting to develop a gene-amplifying technique similar to PCR. In a test tube, you place a DNA sample, free nucleotides, human DNA polymerase, and the appropriate primers for the DNA sequence being analyzed. You first heat the sample to 90°C, then cool it to 50°C, and then reheat it to 70°C. Based on this scenario and your knowledge of how modern PCR works, the result of these procedures will be

Accepted Answer

A)   unsuccessful, because the enzyme will denature during the second step (cooling) .
B)   successful copying of the DNA, because it follows modern PCR procedures almost perfectly.
C)   unsuccessful, because the enzyme will denature during the third step (reheating) .
D)   unsuccessful, because the enzyme will denature during the first step (heating) .
E)   unsuccessful, because human DNA polymerase cannot recognize the primers used.

Question 12

All of the following are goals of biotechnology EXCEPT

Accepted Answer

A)   treating disease more effectively.
B)   improving agriculturally important food plants.
C)   creating humans with higher intelligence levels.
D)   generating economic benefits.
E)   efficiently producing biologically important molecules.

Question 13

Question 14

Sequencing the genes of humans is important because

Accepted Answer
