Explore the primary, secondary and tertiary structure of proteins with the captivating models and tools in this dynamic kit. This engaging, hands-on protein folding kit makes teaching protein structure basics easy. Students will fold a protein while exploring how the chemical properties of amino acids determine its final structure. Students can use the Amino Acid Starter Kit© to: •Learn that the 20 amino acids all share a common backbone but have different side chains, each with different chemical properties. •Identify the chemical properties of the side chains through a dual colouring scheme guided by the kit’s chemical properties circle, amino acid side chain list and coloured plastic clips. •Group the side chains into one of 5 categories: hydrophobic (nonpolar), hydrophilic (polar), negatively charged, positively charged, and cysteines, which sometimes form disulphide bonds. The coloured clip at the base of each side chain indicates chemical properties while embedded coloured balls in the amino acid side chain model show atomic structure. •Employ the kit’s protein-folding activities to first explore the primary and tertiary structure of proteins by constructing a generic 15-amino acid protein, then learn about the secondary structure of proteins by folding a toober model of the first of 3 zinc fingers of the Zif268 protein. Each 1-group set includes 1 chemical properties circle, 1 amino acid side chain chart, 22 amino acids, 1 mini toober, 22 coloured plastic clips and 6 hydrogen bond connectors.

These versatile modelling Toobers provide hands-on learning experiences in biology and chemistry. Students can model DNA or create protein structures and explore basic protein-folding principles. Toobers are flexible foam rods which have soft wire core that allows them to hold their shape well and they can be simply straightened out afterwards and re-used. Length: 120 cm long. Please note that theses are sold individually and the push pins are not included. See also 'Amino Acid Starter Kit' (MO110150). Also useful for teaching: • How hydrophilic/hydrophobic side-chains influence protein's structure • How structure is critical factor in many protein's function

Students will immediately become engaged with this interactive foam model of double-stranded DNA and single-stranded RNA. The DNA Starter Kit© is schematic model that transforms from the familiar ladder shape to the double helix with twist. Students can explore the structure of colour-coded DNA bases showing purines and pyrimidines which connect to continuous sugar-phosphate backbone. Then they can delve into replication and transcription. Using individual nucleotide triphosphates, they can synthesize new strand of DNA one base at time showing the semi-conservative replication of DNA. Finally they can synthesize mRNA one base at time to show the process of transcription. Each kit includes: 51 bases (12 red adenine, 12 yellow thymine, 12 blue cytosine, 12 green guanine, 3 white uracil), 4 continuous grey backbones, 24 grey sugar-phosphates, 12 lavender sugar-phosphates and 48 orange phosphates.

The sky is the limit to what you can teach using these new large-scale, colour-coded foam nucleotides. Begin by teaching the complementary A-T and C-G base pairs and the antiparallel nature of double-stranded DNA. Move on to the flow of genetic information as you teach the basic processes of semiconservative DNA replication and mRNA transcription. You can then stretch students by introducing PCR (polymerase chain reaction) and the Sanger DNA sequencing method -- and much more. 80 Large-Scale Nucleotides: • 20 Red Adenosine • 20 Yellow Thymine • 20 Blue Cytosine • 20 Green Guanine 80 Adhesive-Backed Round Magnets
