Exam Board and Specification Codes: OCR (H420) 

The A-Level Biology course allows you to explore how the body works and discover the secrets which enable humans to survive.

It also explores other organisms such as fish, bacteria and insects in detail. You will discover the clever and intricate functions the body undertakes for key processes such as DNA replication, the cardiac cycle and respiration. You will learn about the latest biological research and technology such as RNA interference and DNA sequencing. There are also plenty of exciting practical activities such as heart dissections, modifying bacteria to make them glow in the dark and amplifying DNA to resolve evolutionary relationships between species.
