POLYNUCLEOTIDE
Polynucleotides are essential components for reproduction, growth and function of all cells. They are used in a huge range of biological processes: 


• they are the constituent units of nucleic acids;

• they are key compounds of energetic metabolism.

Chemically, they derive from a combination of a variable number of nucleotides joined together by covalent links: polynucleotides are essential components for reproduction, growth and function of all cells.
