DNA - RNA

The small DNA-RNA model shows the double helix and how the molecules split at the centre of the base pairs. The DNA-RNA Model includes: 30 colored tubes (Guanine red, Cytosine green, Thymine blue, Adenine gray, Uracil white) 12 white two prong centre, which represents the hydrogen bond between…

DNA Model

The DNA model is suspended on nylon line between two wooden plates. The assembly instructions allow you to build a DNA coded for the first part of the protein lysozyme. The tubes are colored to indicate the type of bond. Contents: 15 base pairs, being one and a half turns of the helix Two types…

RNA 12 Base Kit

Easily assemble this single strand molecule which consists of the 4 bases, as in DNA, and Uracil. The molecular model contains enough material to make all 64 codons and provides hands-on investigation into protein synthesis. The RNA 12 Base molecular kit contents: 3 Uracil (light blue) 3 Adenine…

DNA Double Helix

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria. The…

Giant DNA Model

At nearly 90 cm in height, this DNA Molecule is ideally suited to the classroom environment. Magnetic connectors, representing hydrogen bonds, permit the two strands of the double helix to unzip completely, evoking the mechanism of DNA replication, and RNA synthesis (genetic transcription). Removable…
