Nucleotide bases Study guides, Class notes & Summaries

MCAT BiologyCentral Dogma - correct answer DNA → RNA → Protein Purines - which bases? - how many rings? - correct answer Pyrimidines - which bases? - how many rings? - correct answer Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine." Phosphodiester Bond - correct answer 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) - correct ...
