Nucleic Acid Structure and General Features

ID #2097

I know that nitrogenous bases are flat, planar ring structures. Then, how about nucleotide? Does it have a three dimensional shape?

Yes, the other parts of the molecule have a more "rounded" shape for lack of a better term. Think about a phosphate group, which has a phosphorous atom at its center, circled in all directions by multiple oxygen atoms. That would definitely be more 3-dimensional than a planar ring structure in a nitrogenous base.
