Biological Molecules - OCR vs AQA

Welcome to MyEdSpace! In today’s video, we’re exploring the key differences between AQA Biology and OCR Biology in the Biological Molecules topic. Knowing your exam board and specification is crucial for focused and accurate revision.

In this video, we highlight:
Sugars in DNA vs RNA nucleotides: OCR requires recognising structural differences, AQA does not.
Haemoglobin as a conjugated protein: Essential for OCR but not AQA.
Examples of proteins: OCR specifies fibrous (e.g., collagen, keratin) and globular (e.g., insulin, catalase) examples.
Purines vs Pyrimidines: Required for OCR but removed from AQA's spec.

This video helps you understand what to focus on, ensuring you're prepared for your exam board.
