Demo DNA Nucleotides
Product Code : LSK-BL-10147
Demo DNA Nucleotides (SKU LSK-BL-10147) is a set of 80 large-scale, colour-coded foam nucleotides with 80 adhesive-backed round magnets, made for whole-class demonstrations of DNA base pairing, replication and transcription. Teachers can arrange the pieces into strands in front of students and rearrange them as the lesson moves on. Buyers in schools, colleges and distribution can obtain the set through Science Lab Supplies, which quotes it from its office in Ambala, India.
Specifications
The table lists the contents of the nucleotide demonstration set piece by piece. In short, there are 20 nucleotides each of red adenosine, yellow thymine, blue cytosine and green guanine, all in foam at a large scale, plus 80 adhesive-backed round magnets for attaching them during a lesson.

Applications and Experiments for the Demo DNA Nucleotides
The nucleotides let a teacher build DNA in front of the class and then take it apart again. Lessons can begin with A-T and C-G pairing and the antiparallel strands, move to semiconservative replication and mRNA transcription, and stretch advanced students towards PCR and the Sanger sequencing method.
- Class 12 biology (Molecular Basis of Inheritance): complementary base pairs, antiparallel strands and semiconservative replication.
- Transcription: laying out an mRNA copy against a DNA template strand on the board.
- Biotechnology units: explaining PCR before students handle reagents such as PCR Beads and view stained gels on a White Light Box.
- B.Sc. genetics: walking through the Sanger sequencing method one base at a time, then building a 3D helix with the DNA Model Kit.
Standard Scope of Supply
Each set holds 80 foam nucleotides, made up of 20 red adenosine, 20 yellow thymine, 20 blue cytosine and 20 green guanine, together with 80 adhesive-backed round magnets. A magnetic board and laboratory reagents are not included and can be requested as separate items on the quotation.
Packing, MOQ and Lead Time
One set covers a teacher's demonstrations, while extra sets let several sections run the same activity at once. Tell Science Lab Supplies how many you need and the quotation will give packing, delivery time and price for that exact number, with any other genetics items added beside it.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Start an enquiry from the contact page, add the set to the enquiry cart, or visit the lab tender page if you are preparing a formal tender.
Frequently Asked Questions
How many of each base are in the set?
There are 20 of each: red adenosine, yellow thymine, blue cytosine and green guanine, giving 80 large-scale foam nucleotides in total, enough to lay out long complementary strands on a board.
What are the magnets for?
The set includes 80 adhesive-backed round magnets, one for each nucleotide. Once fixed to the foam pieces, they let the teacher place and move nucleotides on a magnetic board while building and splitting strands.
Which topics can be taught with the nucleotides?
Base pairing, antiparallel strands, semiconservative DNA replication and mRNA transcription can all be shown, and more advanced classes can use the same pieces to explain PCR and the Sanger DNA sequencing method.
Who supplies the Demo DNA Nucleotides?
Orders for this set are handled by Science Lab Supplies, based in Ambala, India. The team prepares quotations for schools, colleges, distributors and tender contractors and can bundle the set with other DNA models.
