Antigens and cell recognition
Antigens and cell recognition
Cells carry surface molecules, mainly proteins, with precise tertiary structures. These molecules act like identity labels, allowing the immune system to distinguish self from non-self.
Step-by-step lessons on AQA A Level Biology Cell recognition and the immune system, covering Cell recognition and the immune system. 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.
