Central Dogma DNA → RNA → Protein Purines - which bases? - how many rings? Pyrimidines - which bases? - how many rings? Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine." Phosphodiester Bond Joins one nucleotide to the next; between the 3rd C of one ribose and the 5th C of the other to create the sugar-phosphate backbone Directionality of DNA (convention) 5' → 3' (but strands are antiparallel, so other strand is opposite) 3' of DNA atta...
