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.
In DNA, the monomers are called nucleotides, and these are linked together to form a polynucleotide chain that can be hundreds, thousands, or even millions of nucleotides in length. First we will study the structure of a nucleotide, and then we will examine how nucleotides are joined together to form a polynucleotide.
