Nucleic acids are key biomolecules in the continuity of life.

Because of this slight positive charge, the hydrogen will be attracted to any neighboring negative charges. Responsible for capillary action). This diversity of molecular forms accounts for the diversity of functions of the biomolecules and is based to a large degree on the ability of carbon to form multiple bonds with itself and other atoms.
