Genetics Revision Notes

Specification Link

This genetics diagram is used for: Give a clear account of the inheritance of the ABO blood groups with reference to codominance and multiple alleles.

What To Explain

DNA is organised into genes and chromosomes, so the diagram should be linked to inherited information.

Exam Answer Move

This is aligned to: Give a clear account of the inheritance of the ABO blood groups with reference to codominance and multiple alleles. The learner should connect the visual to genetic information, inheritance or variation as required by the objective.

Specification Link

This digestive system diagram is used for: Build an explanation of the way the order of bases in a section of DNA decides the order of amino acids in the protein and that these fold to produce specifically shaped proteins for example enzymes.

What To Explain

Digestive organs and enzymes break large insoluble food molecules into smaller soluble molecules that can be absorbed.

Exam Answer Move

This is tied to: Build an explanation of the way the order of bases in a section of DNA decides the order of amino acids in the protein and that these fold to produce specifically shaped proteins for example enzymes. The learner should explain digestion, enzymes or absorption.

Recognising Protein Quaternary Structure

Protein Quaternary Structure supports DNA, Amino Acids, and Protein Folding by giving students a diagram they can connect to the specification point being tested.

What To Explain

The membrane is selectively permeable, so substances move across it by diffusion, osmosis or active transport depending on the particle and gradient.
