... KEY CONCEPT DNA structure is the same in all organisms. DNA is a chain of nucleotides. In DNA, each nucleotide is made of a phosphate group, a sugar called deoxyribose, and one of four nitrogen-containing bases. These four bases are cytosine (C), thymine (T), adenine (A), and guanine (G). Two of the ...
