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. |
