Molecular models of DNA - Wikipedia The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as the wire, or skeletal, type shown at the top of this article, allow one to visually explore the three-dimensional (3D) structure of DNA. Another type of DNA model is the space-filling, or CPK, model. The Structure of DNA - University of Arizona A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P) And one of four nitrogen-containing molecules called nucleotides . (Labeled A, T, C, or G) Alternating sugar and phosphate units form the two sides of a ladder-shaped arrangement with the rungs or steps each formed by a pair of nucleotide bases.
DNA Model - nau.edu DNA Model DNA MODELS DUE: This week you will construct a 3-D model of DNA out of household junk. Make sure that you include the sugar-phosphate backbone and the nitrogen bases. These beautiful works of art and science will hang in ...
