Biology Year 12 - Module 5 - Lesson 12
Proteins, Phenotype and Gene-Environment Interaction
1. Key Ideas
Genes do not produce traits directly. Genes influence protein structure and protein function, and those protein effects contribute to phenotype. Environment can also influence how phenotype is expressed.
- Major functional categories of proteins in living things.
- Why phenotype is not determined by genes alone.
2. Success Criteria
By the end, you should be able to:
- Major functional categories of proteins in living things.
- That genotype influences phenotype through protein production and function.
- Why phenotype is not determined by genes alone.

5. Short Answer Questions
1. Explain this lesson goal in your own words: "Major functional categories of proteins in living things.". Use one specific example from the lesson.
2. Apply this idea to a new example: "That genotype influences phenotype through protein production and function.". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Proteins, Phenotype and Gene-Environment Interaction: "Why phenotype is not determined by genes alone.".
6. Extend: Apply the Idea
A student gives a memorised answer about Proteins, Phenotype and Gene-Environment Interaction but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.

A. Identify the key concept being tested
B. Write every fact from memory
C. Ignore the command word
D. Skip examples and evidence
2. Which answer would show stronger understanding of Proteins, Phenotype and Gene-Environment Interaction?
A. An answer with accurate terms and reasoning
B. A copied definition only
C. A single-word response
D. An answer with no example
3. What should you do if a question asks you to explain?
A. Link the idea to a reason or cause
B. List unrelated facts
C. Only draw a diagram
D. Write the shortest possible answer
8. Success Criteria Proof
Finish with evidence that you can do each success criterion.
