HIV virus model is enlarged millions of times, shows the outer lipid membrane with protein structures and the internal nucleus which contains the viral hereditary matter. The nucleus is removable, supplied with stand and key card.

Set of 15 newly designed models according to the recent concept of chromosome changes from the resting nucleus to the formation of 4 daughter cells,complete set mounted on board.

This Orbit molecular model aids understanding of the process of DNA-RNA transcription.The model shows 12 base pairs with each base (guanine, cytosine, thymine, adenine and uracil) in a different colour and the sugar rings, phosphate groups and hydrogen bonds in black, red and white respectively. Suf...

A set of 10 models showing resting cell, early prophase, prophase, late prophase, metaphase, late metaphase, anaphase, late anaphase, telophase and daughter cells, all mounted on board with Key Card.

A set of 12 models, showing detailed stages in meiotic cell division, realistically coloured to bring out the detailed structures as seen under a microscope. A very useful and instructive model, mounted on board, with key card.

A set of 10 models showing all the stages of karyokinesis and cytokinesis from metabolic cell to the formation of two daughter nuclei. All stages are mounted on a board, with key card.

A Three dimensional model with one side dissected to show complete internal structures,mounted on base,with key card.

Molecule model kit for a right-handed double helix with colour-coded components for representing the bases containing nitrogen as well as pentoses and phosphate groups from which DNA is composed. Can be used to demonstrate DNA replication in model as well as complementary base pairing.Advantages· S...

A model of a typical Animal Cell, 20,000x magnification. Shows structure & cell organelles. 42x30x16cm on base. Made from high quality PVC with European styling.

This two-piece colourful and robust PVC animal cell model shows the form and structure of a typical animal cell as viewed by an electron microscope. For purposes of better illustration, all important organelles are shown in raised relief and displayed in colour:• Nucleus• Mitochondrion• Smooth...

Easily assemble this single strand molecule which consists of the 4 bases, as in DNA, but instead of Thymine it has Uracil. This RNA molecular kit contains 12 bases, equivalent to 4 codons in a single strand model of messenger RNA as well as 2 "clover leaf" shaped Transfer RNA parts and 2 amino-acid...

A simple model of the Covid 19 Virus demonstrating the exterior surface. The bulbous projections seen on the outside of the Corona virus are spike proteins (red). This fringe of proteins gives the virus its crown-like appearance from which the Latin name corona is derived. The spike proteins act as ...
