Sobre este producto

[HIGHLIGHTING DNA STRUCTURE] DNA molecules are formed by two glycine chains spiraling around the helix, with and deoxyribose in an alternating arrangement. [REVERSE PARALLELISM DEMONSTRATION] Two glycine chains run in opposite directions, showcasing the unique properties of DNA composition. [DETAILED STRUCTURAL DESIGN] The model accurately represents the positioning of monosaccharide , base pairs, and deoxyribose in the DNA structure. [EMPHASIZING BASE PAIRING] The base pairs of A-T, G-C, and A-T are clearly illustrated with hydrogen bonding displayed in a vibrant red casing. [IDENTIFICATION OF MAJOR AND GROOVE] The model showcases the major and grooves of the double helix, providing a comprehensive visual aid for biology education. Spec: Item Type: DNA Structure Model Material: Plastic Model Structure: 1. Double helix with a diameter of 10A; 2. Pitch 18A, distance between adjacent base pairs 1.8A; 3. The difference in direction of adjacent bases is 360; 4. 6 pairs of base pairs per pitch; 5. The hydrogen length is 1.0-2.5A. Application: The product meets the national standard JY35 81 "DNA Structure Model Technical Conditions" produced by the Ministry of Education, and is suitable for teaching biology as a basic course in ordinary high schools and universities.
