GENETICS: CELL DIVISIONS / STRUCTURE & FUNCTION OF DNA |
Mitosis model |
This newly developed 3B Scientific ® model series shows the following 9 phases of mitosis on the basis of a typical mammal cell at an enlargement of approx. 10,000 times: 1. Interphase 2. Prophase 3. Early prometaphase 4. Later prometaphase 5. Metaphase 6. Early anaphase 7. Later anaphase 8. Telophase 9. Cytokinesis The three-dimensional relief models are painted according to the usual coloring methods of microscopy, making the process of cell division easy to understand. The cell organelles are shown as if opened up in the lower part of the models. The models are equipped with magnets at the back so that for teaching purposes they can be easily arranged on a magnetic board in the classroom. The model series is supplied in a storage system (40 x 60cm) which can be fastened to the wall. A detailed description and handouts for your lessons are included. |
Item # APPR01 |
Qty 1 = $373.00 ea |
Meiosis Model |
This newly developed 3B Scientific® model series shows the 10 stages of meiosis on the basis of a typical mammal cell at an enlargement of approx. 10,000 times: 1. Interphase (stage of G1-phase) 2. Prophase I (leptotene) 3. Prophase I (zygotene and pachytene) 4. Prophase I (diplotene) 5. Prophase I (diakinesis) 6. Metaphase I 7. Anaphase I 8. Telophase I, cytokinesis I, interkinesis, prophase II and metaphase II 9. Anaphase II 10. Telophase II and cytokinesis II The three-dimensional relief models are painted according to the usual coloring methods of microscopy, making the process of meiotic cell division easy to understand. The cell organelles are portrayed open in the lower part of the models. The models are equipped with magnets at the rear so that they can be easily arranged on a magnetic board in the classroom. The model series is supplied in a storage system (40 x 60 cm) that can be hung on a wall. Supplied with a detailed description and handouts to copy for your lessons. |

Nucleic Acid Building Blocks |
Coloured units (representing phosphoric acids, purines and pyrimidines) for constructing DNA, t-RNA and RNA helices. Also useful for explaining replication and transcription. |
Item # APPW19204 |
Qty 1 = $389.00 ea |
DNA Double Helix |
3 coils of the DNA double helix, consisting of nucleic acids, to demonstrate base pairing. At the top end is attached one RNA cord, to show the basis of transcription. On base. |
Item # APPW19205 |
Qty 1 = $169.00 ea |
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 nucleotides let students experience first hand why a larger purine base must always pair with a smaller pyrimidine base, and that base pairs are complementary - adenine pairing with thymine and guanine pairing with cytosine. Non-separable atoms connected by permanent flexible “bonds” form the sugar-phosphate backbone of the molecule. Encompassing six base pairs the double helix is mounted on a wooden base and can be rotated. |
