Unlike the protein α-helix, where the R-groups of the amino acids are positioned to the outside of the helix, in the DNA double-stranded helix, …
WebDNA backbones are made up of deoxyribose, a pentose sugar. These sugars are connected via a phosphodiester bond. The phosphate groups have a negative charge to them, which allows positively charged histone proteins to interact with them in forming chromatin. Also helps separate DNA with gel electrophoresis.
