And likewise, if this was deoxyribose and guanosine, we'd call it deoxyguanosine and so forth. So these are the four nucleotides found in RNA and these are the four nucleotides found in DNA molecules. And notice that the linkage between the carbon found on the sugar and the nitrogen found on our base is the beta glycosync linkage. Now this bond here is also coming out of the board. And what that means is if this sugar molecule was found on the plane of the board, this entire base will be found above the plane of that sugar. And so what that means is the base group, in this case it's the adenine, lies above the plane of the sugar molecule.
