I want to know the answer to the following question:
Besides the sugar and the four bases, what else does DNA consist of?
All the background I'm provided with is that "DNA consists of a chain made from four types of nucleotide subunits, each composed of: a five-carbon sugar (2'-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine.:2.1". Is that enough to answer the question?
