A polynucleotide is a nucleic acid molecule consisting of a long chain of nucleotides. Nucleotides in a polynucleotide molecule are held together by a bond between the phosphate group of one nucleotide and the sugar of a second nucleotide, which is called a phosphodiester bond.
These nitrogenous bases in conjugation with a deoxyribose sugar, are called nucleosides. When they gain one or more phosphate groups, they are then termed as nucleotides. Nucleotides use these phosphate groups to link together via the formation of phosphodiester bonds, and bond to their complementary bases using hydrogen bonds. Due to the presence of deoxygenated ribose sugars, the structure, DNA, is called deoxyribonucleic acid. The four bases can be divided into two categories based on their chemical structures.
