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. So when we normally draw nucleotides, this is how we portray our nucleotide. So all a nucleotide is it's basically the nucleotide minus the phosphate group. So the way that we define a nucleotide is basically by saying we have a nucleotide that contains at least one phosphate group.
