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 a 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

Polymerase chain reaction (PCR) is a technique used to amplify small segments of DNA, making it possible to generate millions of copies of a specific DNA sequence from a small initial sample, which would be essential for testing the limited amount of dodo DNA available.
