DNA

• The monomer for DNA are nucleotides therefore known as a polynucleotide
• The structure of DNA are 2 strands of nucleotides held together by hydrogen bonds in a double helix

  
• A nucleotide is made up of :

  (Bases= A-T , C-G)

  A) Phosphorus group

  B) Deoxyribose Sugar

  C) Base

  
• Different orders of the bases encodes genetic info into DNA
• DNA is made through Condensation Polymerisation
