DNA Model Home Studies/Geek Gift

This is our most basic DNA molecular model but it still shows all the important  details including complementary base pairs & stands 450mm or 18" tall.

The image has been produced as a stereo pair; click on the image for an enlarged version & then cross your eyes to see it in 3D.

Note that the relative sizes of the major & minor grooves is exaggerated for effect. For more precisely build models, see our 12 base pair DNA model or our DNA double helix model, 17 base pairs.

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.
