Cell Biology Models

This model compares the structures of Taenia saginata and Taenia solium scolex; the anatomy of the proglottid is shown through the longitudinal section at three different stages of maturation: immature, mature and gravid proglottid. Significant structures, such as suckers, hooklets, uterus and testis, are numbered and referenced on the accompanying key-card

This item is composed of 12 different pieces showing the main stages of the mammal cell meiosis (prophase I, metaphase I, anaphase I, telophase I, cytokinesis I, prophase II, metaphase II, anaphase II and cytokinesis II) at an enlargment of approx. 10000 times. During all stages you can see the different characteristics of the cellular structures such as chromosomes, centrioles, spindle and nucleus. Every single piece is numbered to indicate the correct sequence of steps.

This item is composed of 9 different pieces showing the main stages of the mammal cell mitosis (prophase, metaphase, anaphase and telophase) at an enlargement of approx. 10000 times. During all stages you can observe the different characteristics of the cellular structures such as chromosomes, centrioles, spindle and nucleus. Every single piece is numbered to indicate the correct sequence of steps.

This self assembly kit contains all the blocks needed (stand included) to build a 12 base pairs right handed double helix DNA (B-DNA). Parts are colour coded and have characteristic shapes, with deoxyribose being pentagonal, phospates cylindrical and nitrogenous bases showing their pyramidine or purine structure. Two different central connecting parts depict the 2 and 3 H-bond between Thymine/Adenine and Cytosine/Gaunine.
The assembled model is important in demonstarting the most peculiar features of double stranded DNA structure and topology.
