Genetics Revision Notes

Specification Link

This genetics diagram is used for: Explain monohybrid inheritance using genetic diagrams, Punnett squares and family pedigrees.

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: Explain monohybrid inheritance using genetic diagrams, Punnett squares and family pedigrees. The learner should connect the visual to genetic information, inheritance or variation as required by the objective.

Recognising Protein Quaternary Structure

Protein Quaternary Structure supports Understanding DNA Structure 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.

This is linked to: Give a clear account of DNA as a polymer made up of: a two strands coiled to form a double helix b strands linked by a series of complementary base pairs joined together by weak hydrogen bonds c nucleotides that consist of a sugar and phosphate group with one of the four distinct bases attached to the sugar. A strong answer names the transport process and links it to membrane structure.
