- DNA STRUCTURE: DNA molecules are formed by two polynuclear glycine chains spiraling around the same axes with the right hand . The main chain is an alternating arrangement of (P) and deoxyribose (D).
- STRUCTURAL 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.
- REVERSE PARALLELISM: Two polynuclear glycine chains are opposite and parallel, with one chain ranging from 5 to 3 and the other chain ranging from 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) side of the top deoxyribose is facing upwards, while the other side is facing downwards. (P) is also in the opposite direction.
- BASE PAIRING: The bases on two chains form base pairs through oxygen s, and the complementary relationship between base pairs is A‑T, G‑C, and A‑T with three pairs of hydrogen s. The red casing on the model represents hydrogen ing.
- MAJOR AND : The of the double has two obvious concave , one large and deep, and the other small and shallow. They are called the major and , respectively.
