DNA Detective
The Caiman Caper Part 2
High-Tech Machines

FirstI took samples of the reptile skins to my lab at the American Museum of Natural History. There I used some high-tech machines to separate the DNA from everything else.

ThenI made lots of copies of the DNA, so it was easier to study.


NextI used a machine to figure out the DNA’s sequence, which looks like a long string of letters. Every animal species has its own DNA pattern. Geneticists can match DNA patterns the same way police match fingerprints.
