Last updated: 18 October 2026
Key Features
Reveals a double strand of DNA.
Shows how a gene is duplicated.
Models a mutation that changes the normal form into the sickle-cell form.
The double strand and gene duplication are 2 of the 7 classroom demonstrations the model supports.
Classroom demonstrations: 7
How It Is Used
The teacher uses the model in front of the class to open out the DNA double strand, duplicate a gene, and then introduce a mutation to show how a change in the genetic code leads to sickle-cell blood.
Laboratories and education suppliers in North Macedonia, Djibouti, Zimbabwe, Bangladesh, Zambia and Palestine can source the Model: DNA from JLab India for export.
