WebMar 1, 2024 · In their first attempt at a structure of DNA, Watson and Crick formulated a triple helix consisting of three polynucleotide chains. They placed the intertwined sugar-phosphate backbones on the inside and the bases (adenine, cytosine, guanine, and thymine) on the outside of the backbones (Watson, 1968, p. 79). WebDec 18, 2024 · The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn’t contain thymine bases, replacing them with uracil bases (U), which pair to adenine 1.
