When used as part of a lab exercise, it is highly effective for illustrating the major features of the double helix as well as explaining the basics of DNA forensics identification techniques. 12 base pairs is enough to show 1 full turn & is sufficient to illustrate the nature of unique DNA sequences needed for forensic analysis.

This model has been training molecular biologists since 1997. Among our many customers: U. Toronto, Harvard, MIT, NYU, U. Minnesota, Wayne State, U. Illinois, Caltech, US Naval Academy, Stanford & many more.


TV & movie appearances include the Fantastic Four & Stargate Atlantis!
