Overview

We've been making DNA and molecular biology models at schoollabmanufacturers.com since 1996, shipping to school and college labs across 75-plus countries. The idea is simple — let students actually build the stuff themselves instead of just staring at diagrams. Our SLM-DNA-75 atom model set lets them assemble a DNA double helix from scratch, which happens to be exactly what WAEC, KNEC and Cambridge IGCSE biology practicals want them to do. Everything's made from colour-coded ABS plastic that clicks together properly, so base-pairing and molecular geometry actually look right when they're done.

Products We Supply

• DNA double helix model assembled (SLM-DNA-DH) — 45cm tall, colour-coded bases, sugar-phosphate backbone, shows 12 base pairs.
• DNA atom model set 75-piece (SLM-DNA-75) — For student assembly. All nucleotides and bases included, colour-coded by base type.
• DNA atom model set 200-piece (SLM-DNA-200) — Extended set if you need to demonstrate full chromosome-level structure.
• RNA model (SLM-RNA-1) — mRNA single strand, 12 codons shown, colour-coded.
• Amino acid model set (SLM-AA-20) — All 20 essential amino acids, demonstrates peptide bond assembly.

• Protein structure model (SLM-PRO-1) — Shows primary, secondary (alpha helix) and tertiary structure.

• Enzyme-substrate model (SLM-ENZ-1) — Lock-and-key mechanism, active site visible.
• Cell division (mitosis) model (SLM-MIT-1) — Four stages of mitosis with chromosome movement.
• Meiosis model (SLM-MEI-1) — Eight stages of meiosis, including chromosome crossing over.
• Genetics inheritance model — Dominant and recessive allele demonstration set.

Why Buyers Choose schoollabmanufacturers.com

• WAEC molecular biology compliant — DNA models are on the WAEC biology SS3 apparatus list.
• KNEC genetics and molecular biology compliant — DNA and protein models cover KCSE Form 3-4 requirements.
• Cambridge IGCSE Biology 2.2 compliant — DNA structure models for IGCSE molecular biology.
• Student-assembly sets build deeper understanding — Students learn more building it themselves than looking at a finished model.
• Colour-coded components — Follows international convention: A=green, T=red, G=blue, C=yellow.

Frequently Asked Questions

Which DNA model is suitable for WAEC biology SS3 molecular genetics?

The SLM-DNA-75 atom model set is what you want. Students can assemble the double helix, practise base-pairing rules (A-T, G-C) and work through replication — all the core WAEC biology practical competencies. The pre-assembled SLM-DNA-DH model works well for classroom demonstration alongside it.

Can students use your DNA model sets to complete Cambridge IGCSE biology practicals?

Yes. Our DNA atom model sets line up with Cambridge IGCSE Biology specification points 2.22 (DNA structure) and 2.23 (DNA replication). Students can use the SLM-DNA-75 set to complete the practical activities in the Cambridge IGCSE Biology coursebook.
