Protein synthesis
Lesson 6 GCSE Triple Science
Module 14
Lesson objectives:
1. You will understand the role of DNA in
deciding protein structure
2. You will understand the 3 stages of protein
synthesis
Starter activity:
Copy and complete questions
1. What does DNA stand for?
2. What is DNA made up from?
3. What are the four bases of DNA called?
4. How many bases make up the code for one
amino acid?

Protein synthesis:
3 important stages in protein synthesis:
• The coding by triplets of bases to produce
mRNA (Transcription)
• The linking of mRNA to tRNA at ribosomes
(Translation)
• The linking of amino acids to form
polypeptides
Transcription of mRNA
Translation of mRNA to make protein
Overview of protein synthesis
Activities:
Use a range of websites to produce:
1. An annotated flow chart showing the stages of
protein synthesis.
2. Publish you work on your own website pages! (to
go on school site )
Two sites below will help

synthesis: Revision Intro
Plenary:
Present your website pages to the class for peer
assessment. Presentation should be no more
than five minutes and cover all the stages of
protein synthesis.
Your web-pages will be judged on:
• scientific content
• web design
• originality of material
