DNA, RNA and genes

Labelled comparison of DNA double helix and single-stranded RNA showing sugar-phosphate backbone, deoxyribose, ribose, base pairs, hydrogen bonds and strand direction DNA stores genetic information in genes, which are sequences of bases that code for a polypeptide or a functional RNA. Proteins made from these instructions act as enzymes, receptors, channels or structural molecules.

Step-by-step lessons covering Edexcel A A Level Biology DNA, RNA and protein synthesis for A Level Biology. Each lesson 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.
