In this video, I take you through the essential information about nucleotides. First I show you the three parts of a nucleotide. I then take you through the differences between the sugars and bases found in the nucleotides which form DNA and RNA. Finally I explain to you how nucleotides can be joined to form polynucleotides by forming a phosphodiester bond.

This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
