22 Layer mini-DNA Model

This model appears to be the simplest of the 3 that we sell, but the 22 base pairs theoretically allow for over 17 trillion combinations. This makes it quite useful for teaching the theory behind dna forensic fingerprinting, especially the touch DNA method. This technique flows from a refinement of the PCR (polymerase chain reaction) which now only requires 7-8 skin cells to identify someone.

Although the actual base pair sequences analyzed for DNA fingerprints are much longer than 22, students will appreciate that because the touch DNA method relies on 13 specific DNA locations, the overall chance of misidentification is very small.
