One chemical theme across life

Schematic showing four monomers joining by condensation to form a polymer with three water molecules released, and hydrolysis using three water molecules to split the polymer back into monomers

Living organisms look very different, but they are built from a small set of similar biological molecules. Many of these larger molecules are assembled from smaller repeating units.

Step-by-step lessons on AQA A Level Biology Monomers and polymers, covering Monomers and polymers. Each one builds up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
