1. DNA STRUCTURE: DNA molecules are formed by two polynuclear glycine chains spiraling around the same axes with the right hand helix. The main chain is an alternating arrangement of (P) and deoxyribose (D).2. REVERSE PARALLELISM: Two polynuclear glycine 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.3. STRUCTURAL DETAILS: The main chain composed of monosaccharide is located on the outer side of the helix, the base is located on the inner side, the deoxyribose is parallel to the axes, and the base is basically perpendicular to the axes.4. BASE 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.5. MAJOR AND : The of the has two obvious concave , one large and deep, and the other small and shallow. They are called the major and , respectively.Spec:Item Type: DNA Structure ModelMaterial: PlasticModel Structure:1. with a diameter of 10A;2. Pitch 18A, distance between adjacent base pairs 1.8A;3.

• 【UNIQUE DESIGN】gene structure display model. Experience the intricate beauty of DNA with our DNA structure model, which meticulously replicates the iconic shape. This design showcases the two polynuclear glycine chains spiraling around a common axis in a right-handed helix, perfectly capturing the essence of DNA's structure. The precision in detailing the alternating arrangement of and deoxyribose groups along the main chain adds to its visual
• 【REVERSE PARALLELISM FOR REALISTIC REPRESENTATION】dna model stand. Our model excels in demonstrating the reverse parallelism of DNA strands, a crucial feature often overlooked in lesser One strand runs 5' to 3', while the other runs 3' to 5', accurately reflecting the orientation of nucleotides within DNA. The strategic positioning of the deoxyribose oxygen atoms and phosphates in opposite directions enhances the realism of the model, providing insights into the internal
• 【STRUCTURAL CLARITY FOR ENHANCED LEARNING】3d molecular model. The structural details of our DNA model are meticulously crafted to ensure clarity and understanding. The monosaccharide backbone, positioned on the outer side of the helix, provides a sturdy scaffold for the bases located on the inner side. The deoxyribose molecules are parallel to the axes, while the bases are perpendicular, offering a clear view of the base-pairing interactions. This arrangement not only aids in
• 【BASE PAIRING AND HYDROGEN BONDING HIGHLIGHTED】dna structure model. Experience the magic of base pairing and hydrogen bonding with our DNA structure model. The bases on the two chains form complementary pairs through hydrogen with A-T and G-C interactions clearly visible. The red casing represents the hydrogen emphasizing the stability and specificity of base pairing. The A-T pairs, held together by three hydrogen demonstrate the strength of these
