AQA A-level Biology Predicted Paper 3

AQA A-Level Biology Predicted Paper 3 

Our AQA A-Level Biology Predicted Paper 3 has been carefully designed using previous exam trends, topic analysis, specification coverage, and areas that have either been under-assessed or not recently examined.

This challenging 78-mark paper mirrors the style, structure, and application focus of the real AQA Paper 3, helping students identify weaknesses, strengthen exam technique, and gain confidence before the final exam.

Topics Included

Biological Molecules

• Water properties and their biological significance

• Inorganic ions (iron in haemoglobin, phosphate in ATP and DNA, sodium in co-transport)

• Structure-function relationships of carbohydrates including cellulose, glycogen, and starch

Cells

• Cell fractionation and ultracentrifugation

• Magnification calculations

• Comparison of optical microscopes, TEM and SEM

• Prokaryotic and eukaryotic cell structure

• Mitotic index calculations

Exchange and Transport

• Haemoglobin and oxygen dissociation curves

• The Bohr effect

• Surface area to volume ratio calculations

Genetics and Variation

• Biodiversity and index of diversity calculations

• Meiosis and genetic variation

• Standard deviation interpretation

Responding to Environments

• Muscle contraction (actin, myosin, tropomyosin and calcium ions)

• Insulin and glucagon regulation through the second messenger model

• cAMP and adenylate cyclase pathways

Genetics, Populations, Evolution and Ecosystems

• Mark-release-recapture calculations

Gene Expression

• DNA methylation and histone acetylation

• Totipotent, pluripotent and multipotent stem cells

• Oncogenes and tumour suppressor genes

• Genetic fingerprinting and gel electrophoresis interpretation

• Gene therapy applications

• Recombinant DNA technology including ligase, vectors, marker genes and transformation
