Biology Year 12 - Module 5 - Lesson 10
Transcription - From DNA to mRNA
1. Key Ideas
Genes stay in DNA, but the instructions for building a protein need a portable copy. Transcription produces mRNA from a DNA template strand so coded information can move on to the next stage of polypeptide synthesis.
- A gene is a DNA sequence that codes for a product.
- Why mRNA is needed as a temporary copy rather than moving DNA itself.
2. Success Criteria
By the end, you should be able to:
- A gene is a DNA sequence that codes for a product.
- Transcription forms mRNA from a DNA template strand.
- Why mRNA is needed as a temporary copy rather than moving DNA itself.

5. Short Answer Questions
1. Explain this lesson goal in your own words: "A gene is a DNA sequence that codes for a product.". Use one specific example from the lesson.
2. Apply this idea to a new example: "Transcription forms mRNA from a DNA template strand.". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Transcription - From DNA to mRNA: "Why mRNA is needed as a temporary copy rather than moving DNA itself.".
6. Extend: Apply the Idea
A student gives a memorised answer about Transcription - From DNA to mRNA 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.
