{"product_id":"b0dfpz71rz","title":"DNA Model Kit for Biology Teaching – Plastic Structure with 5' to 3' Directional Chains, Major Groove Detail – DNA Structure Model for Classroom and Lab Use","description":"\u003cdiv\u003e\n\u003ch1\u003eAbout This\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eBASE PAIRING: The bases on two chains form base pairs through oxygen , and the complementary relationship between base pairs is A‑T, G‑C, and A‑T with three pairs of hydrogen . The red casing on the model represents hydrogen bonding.\u003c\/li\u003e\n\u003cli\u003eMAJOR AND GROOVE: The appearance of the double has two obvious concave grooves, one large and deep, and the other small and shallow. They are called the major and groove, respectively.\u003c\/li\u003e\n\u003cli\u003eSTRUCTURAL DETAILS: The main chain composed of monosaccharide is located on the outer side of the , the base is located on the inner side, the deoxyribose is parallel to the axes, and the base is basically perpendicular to the axes.\u003c\/li\u003e\n\u003cli\u003eREVERSE PARALLELISM: Two polynuclear chains are reverse parallel, with one strand running 5 to 3 and the other strand running 3 to 5 when viewed from one main direction. On the model, it can be seen that there are 5 to 3 chains The oxygen (0) of the deoxyribose on the top is facing upwards, while the other one is facing downwards. (P) is also in the opposite direction.\u003c\/li\u003e\n\u003cli\u003eDNA STRUCTURE: DNA molecules are formed by two polynuclear chains spiraling around the same axes with the right hand . The main chain is an alternating arrangement of (P) and deoxyribose (D).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hyuduo","offers":[{"title":"Default Title","offer_id":47690138452052,"sku":"SPH-B0DFPZ71RZ","price":214.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/31ZRNdmUBzL._AC_SL1500_a15819e8-3fc0-4400-8905-db973f458ba2.jpg?v=1789644957","url":"https:\/\/learnbrightminds.com\/products\/b0dfpz71rz","provider":"BrightMinds","version":"1.0","type":"link"}
