The second rule holds that both %A ~ %T and %G ~ %C are valid for each of the two DNA strands. This describes only a global feature of the base composition in a single DNA strand. It makes sense that in the context of dsDNA, that A = T and C = G, but I don't see an obvious reason why in a single strand of DNA, A ~ T and C ~ G. lder scrolls tabletop adventure

"WebMar 5, 2024 · The double helix shape of DNA, together with Chargaff’s rules, led to a better understanding of DNA. DNA, as a nucleic acid, is made from nucleotide monomers, and the DNA double helix consists of two polynucleotide chains. Each nucleotide consists of a sugar (deoxyribose), a phosphate group, and a nitrogen-containing base (A, C, G, or T). " - Chargraff's rule
