WebJan 19, 2024 · Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder. WebThe Structure of DNA (The Double Helix) DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine). ... In this model of a very short section of DNA you can see how the A-T and C-G base pairs make up the rungs of the ladder ...
