Built a model showing the structure of dna

WebLinus Pauling, then the world's leading physical chemist, had recently discovered the single-stranded alpha helix, the structure found in many proteins, prompting biologists to think of helical forms. Moreover, he had pioneered the method of model building in chemistry by which Watson and Crick were to uncover the structure of DNA.

WebThe 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 … WebThe structure is fairly simple, resembling a twisted ladder. To make a 3D model, we need to make two strands―sugar and phosphate―and then pairs of nitrogenous bases―adenine and thymine and cytosine and guanine. Just attach the bases like steps of a ladder between the two strands, twist them, and your DNA model is ready!
