DNA
A nucleotide is made up from a phosphate ion bonded to 2-deoxyribose which is in turn bonded
to one of the four bases adenine, cytosine, guanine and thymine.
The NH highlighted in blue are the atoms which bond with the 2-deoxyribose molecule. You
need to learn this.
The nucleotides join to form a polynucleotide chain. Covalent bonds form between the
phosphate group of one nucleotide and the deoxyribose sugar of another one. This makes up
