nucleic acid

• nucleic acid


  are the biopolymers or large biomolecules, essential to all known forms of life.
• nucleic acid


  they are composed of nucleotides which are monomers made of three components: 5-carbon sugar, phosphate group, and nitrogenous base.
• Friedrich Miescher


  discovered nuclein in 1869
