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 covering AQA A Level Biology Monomers and polymers for A Level Biology. Each lesson breaks down Monomers and polymers, then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. 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.
