AQA A-Level Biology: Gene Mutation & Protein Structure (8.1) Lesson

This fully-resourced and engaging lesson is designed specifically for teachers delivering point 8.1 of the AQA A-Level Biology specification. It provides all the tools needed to guide students through how changes in the DNA sequence may or may not alter protein structure, building on prior knowledge of gene mutations introduced in Topic 4.

Key Features:

• Comprehensive Lesson Content: Covers substitution, deletion, and addition mutations in depth, with additional focus on translocation, inversion, and duplication mutations.
• Engaging Activities: Includes a quiz integrated throughout the lesson to reinforce key terminology, such as genetic code properties, mutation types, and mutagenic agents.
• Clear Explanations: Focuses on the degenerate and non-overlapping nature of the genetic code, supporting students’ understanding of why some mutations affect the primary structure of proteins while others do not.
• Curriculum Links: Connects to later sections of Topic 8, demonstrating how DNA mutations can disrupt gene expression.

This resource is ideal for teachers looking for a structured, engaging, and curriculum-focused lesson to support their delivery of AQA A-Level Biology.
