DNA

DNA is Made of Nucleotides that contain a Sugar, a Phosphate and a Base 

• DNA is a polynucleotide - it's made up of lots of nucleotides joined together.
• Each nucleotide is made from a pentose sugar (5 carbon atoms), a phosphate group and a nitrogenous base.
• The sugar in DNA nucleotides is a deoxyribose sugar
• Each nucleotide has the same sugar and phosphate. The base on each nucleotide can vary though.
• There are four possible bases - adenine (A), thymine (T), cytosine (C) and guanine (G)
