A paleontologist has recovered a bit of tissue from 500 years old preserved skin of an extinct bird. The researcher would like to compare DNA from the sample with DNA from a living bird. Suggest the technique that would be more useful for increasing the amount of DNA available for testing.
Correct answer: C. Polymerase chain reaction
- A. Gel electrophoresis
- B. RFLP analysis
- C. Polymerase chain reaction
- D. Tissue culture
Explanation
PCR is a technique used to amplify a specific region of DNA, generating millions of copies of that region. This is likely the most useful technique for increasing the amount of DNA available for testing in this scenario. With PCR, even minute amounts of DNA can be amplified to a level where they can be analyzed.
