Topic 2a) The expression of genes in eukaryotes i) Proteins Activity Resources Outline A. Investigation of protein structure using RasMol worksheet Class computer access required. Computers require to have RasMol installed or it can be run from a disc. The molecules folder contains the images required for this activity. These are available in the Student activities. Copy of ID card template Access to computer an advantage Work through the worksheet following instructions and answer questions. B. Investigation of individual proteins ii) Structure and function of RNA A. Role-play of protein synthesis DNA codes, RNA nucleotides, tRNA cards, information cards B. Protein synthesis diagram Protein synthesis diagram C. Completion of ID cards for molecules involved in protein synthesis See structure and function of RNA Copy of ID cards, information cards from previous activity Each student investigates a particular protein and creates an ID card for it. These can then be used to produce a classroom display. Students work in teams to transcribe and translate the DNA code to identify the correct order of amino acids. They can then read cards in groups to find out the roles of each of the molecules involved. Students use information from the above activity to complete the diagram. Students use the information on the cards to complete ID cards in their notes. iii) Transcription and its role in gene expression iv) Translation of mRNA and its role in gene expression 2b) One gene, many proteins 2c) Differentiation in multicellular organisms A. Genetic code quiz Genetic code PowerPoint and copy of the genetic code B. Protein synthesis story board Copy of storyboard template C. Splicing Splicing PowerPoint and template for strips of letters Students simulate splicing of the primary transcript to for sentences. PowerPoint also contains information to allow completion of box 2 of protein synthesis diagram. One gene, many protein worksheet Use the information in the worksheet to complete the diagram. Alternative splicing PDF Further information on alternative splicing with questions for students to consider. Difficult but could be used as an extension for able students. Culture plants from different plant tissues. See also structure and function of RNA activities A. Identification of pre- and posttranslational modifications leading to the production of different proteins B. Alternative splicing A. Tissue culture practical Link to practical in teacher’s guide Students identify amino acids using mRNA codons. Also introduces start and stop codons. Students complete storyboard to show the entire protein synthesis process. i) Meristems and stem cells A. All about stem cells Cards 16+ and worksheets, questions and posters ii) Research and therapeutic value of stem cells C. Discussion of the ethical issues surrounding stem cells Points of view cards 14–16 PDF B. Role-play About the role-play PDF Background information on stem cells PDF Background information on spinal cord injury PDF Role cards Application for clinical trial Stem cells in the news file D. Stem cells in the news Introductory activity into stem cells and their uses. Includes information cards for discussion, questions for consideration, worksheets and ideas to help produce an information poster. Could be used in entirety or in small activities. Students discuss the views of the various people described on the cards. A worksheet is provided to guide the discussion. Also contains a what if …? scenario that students can discuss. Students take on the role of individuals/groups involved in the application for a clinical trial involving stem cells. A whole-class discussion can then follow the completion of the task. A short newspaper clip on potential uses for stem cells with questions to follow.
