About This Product
As a hands-on Biology Lab Equipment activity, students build the double helix themselves and see how the specially shaped, colour-coded ends line up each base pair between the two phosphate strands. Once assembled, the model can be unzipped to show replication and turned on its metal base for classroom display.
