DNA’s sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. The phosphate group is connected to carbon 5′ of the sugar residue of its own nucleotide and carbon 3′ of the sugar residue of the next nucleotide by phosphodiester bonds. The molecular formula of a compound gives us the idea about the elements that make up the particular compound, and the number of atoms of each element present in the compound. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom. Nucleotides join together to form dinucleotides, tri-nucleotides, and so on resulting in the formation of polymers known as polynucleotides. What holds the two helixes in a DNA molecule together?
