Question

two people recently traveled to another country and purchased a few sculptures made of ivory and brought them back to the united states. elephant husk ivory is banned in many parts of the world. the sculptures were found by law enforcement officers and taken in as evidence. while analyzing the evidence, a forensic scientist extracted dna from the ivory and performed a test on it that allowed the dna to be compared to the dna of an elephant. the scientist was able to conclude that the ivory was elephant husk ivory. what biotechnology was used to identify the source of the ivory?

○ dna fingerprinting
○ cloning technology
○ polymerase chain reaction
○ transgenic technology

Explanation:

DNA fingerprinting is a technique used to identify the source of DNA by comparing unique DNA patterns. In this case, the forensic scientist compared the DNA from the ivory to an elephant's DNA to determine the source, which matches the use of DNA fingerprinting. Cloning technology is for creating identical copies, polymerase chain reaction (PCR) is for amplifying DNA, and transgenic technology involves transferring genes between organisms, none of which fit here.

Answer:

A. DNA fingerprinting
