About This Product
Because the colours carry no labels, students first decide which colour stands for which base and then pair them. Taken off its plastic base, this Human System Model kit can be stretched to its full length to demonstrate strand separation.
Frequently Asked Questions
Q1. Are the bases labelled? No. Each of the four nitrogenous bases comes in a different unlabelled colour, so students design their own pair coding.
Q2. Does the model need a centre post? No. It is assembled and then twisted into a double helix instead of being built around a centre post.
