A paleontologist has recovered a bit of tissue from the 400-year-old preserved skin of an extinct dodo (a bird). To compare a specific region of the DNA from the sample with DNA from living birds, which of the following would be most useful for increasing the amount of dodo DNA available for testing?
A)SNP analysis
B)polymerase chain reaction (PCR)
C)electroporation
D)gel electrophoresis

Question

Quizplus · Accepted Answer

PCR (polymerase chain reaction) is a technique that can amplify small amounts of DNA into larger quantities for analysis. This would be the most useful technique in this scenario to increase the amount of dodo DNA available for testing. SNP analysis, electroporation, and gel electrophoresis are not techniques that would increase the amount of DNA available for testing.
