A paleontologist has recovered a minute tissue sample from an extinct dodo. To obtain enough DNA for comprehensive genetic analysis, which technique would be most effective for increasing the quantity of dodo DNA?

  • A: SNP analysis
  • B: Polymerase Chain Reaction (PCR)
  • C: Electroporation
  • D: Gel electrophoresis

Explanation

Polymerase Chain Reaction PCR is a highly effective technique for amplifying small quantities of DNA into millions or billions of copies, making it indispensable for genetic analysis from limited samples like ancient tissues.
