Final answer:
Polymerase Chain Reaction (PCR) is used by researchers studying elephant poaching to amplify specific regions of DNA for further analysis. It helps in identifying the source of ivory and tracking the movement of poached elephant specimens.
Step-by-step explanation:
Polymerase Chain Reaction (PCR) is a technique used by researchers studying elephant poaching to amplify specific regions of DNA for further analysis. By using PCR, scientists can produce millions of copies of the desired DNA sequence, even from small or degraded samples. In the case of elephant poaching, researchers can use PCR to identify the source of ivory and track the movement of poached elephant specimens.
