Protein synthesis Lesson GCSE Triple Science Module 14 Lesson objectives: You will understand the role of DNA in deciding protein structure You will understand the stages of protein synthesis Starter activity: Copy and complete questions What does DNA stand for? What is DNA made up from? What are the four bases of DNA called? How many bases make up the code for one amino acid? This site will help you remember: BBC Education - AS Guru - Biology - Genes an d Genetics - Structure of DNA - Nucleotides Protein synthesis: 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: An annotated flow chart showing the stages of protein synthesis Publish you work on your own website pages! (to go on school site ) Two sites below will help http://www.bbc.co.uk/education/asguru/biology/intr o shtml BBC - Education Scotland - Higher Bitesize Revision - Biology - Cell Biology - RNA and 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 Remember to acknowledge all material used by another author
