Topic 4: Genetic information, variation and relationships between organisms (AQA A-level Biology)

Every one of the lessons included in this bundle is detailed, engaging and fully-resourced, and has been written to cover the content as detailed in topic 4 of the AQA A-level Biology specification. The wide range of activities will maintain engagement whilst supporting the explanations of the content to allow the students to build a deep understanding of genetic information, variation and relationships between organisms.

The following 18 lessons covering the 7 sub-topics are included in this bundle:

4.1: DNA, genes and chromosomes

• DNA in prokaryotes and eukaryotes
• Genes

4.2: DNA and protein synthesis

• Genome, proteome and the structure of RNA
• Transcription and splicing
• Translation

4.3: Genetic diversity can arise as a result of mutation or during meiosis

• The genetic code
• Gene mutations
• Chromosome mutations
• Meiosis

4.4: Genetic diversity and adaptation

• Genetic diversity
