Transcript
Date ______ Protein Synthesis Web Activity Name _______________ Part 1: Practice the processes of transcription and translation. http://learn.genetics.utah.edu/units/basics/transcribe/ Click the button that says “click here to begin.” Use the keyboard to type the bases that would form the mRNA. Follow the instructions to determine the order of the amino acids. 1. List the order of your amino acids._________________________________ ________________________________ ______________________________________________________ 2. How did the process know to end? Read the script on the right side of the webpage. 3. Describe the process of transcription. ______________________________ 4. ______________________________________________________ Describe the process of translation. ________________________________ ______________________________________________________ Part 2: View the protein synthesis animation. http://www.wisc-online.com/objects/index_tj.asp?objid=AP1302 Read the animation page by page – just click the “next” button when you are ready to move on. 5. How does the mRNA leave the nucleus? __________________________ __________________________ 6. Is just one mRNA molecule made? Explain. __________________________ __________________________ __________________________ 7. How many amino acids does each codon code for? ____________________ 8. Describe the structure of a tRNA molecule. __________________________ __________________________ __________________________ ______________________________ 9. In the diagram to the right label the ribosome, mRNA, tRNA, amino acids, anticodon. 10. Where does the energy to form the peptide bond between two amino acids come from? ______________________________________________________ 11. What has been created when all of the amino acids have been brought to the ribosome? ______________________________________________________ 12. After the amino acid chain leaves the ribosome, what happens to the shape of the chain? ______________________________________________________ Date ______ Protein Synthesis Web Activity 13. Can a single mRNA be read more than once? Explain. Name _______________ ____________________ ______________________________________________________ Part 3: Control of Gene Expression http://www-class.unl.edu/biochem/gp2/m_biology/animation/m_animations/gene2.swf Click the right hand arrow to move through the animation. Answer the following questions. 14. Where does protein synthesis begin? _______________________________ __________________________ ______________________________________________________ 16. How is the information above encoded? _____________________________ ______________________________________________________ 17. What is the function of mRNA? __________________________________ ______________________________________________________ 18. What does the promoter do? ____________________________________ ______________________________________________________ 19. What are the three regions of a gene? ______________________________ 20. What does RNA polymerase do? _________________________________ ______________________________________________________ 21. Describe the transcription process in terms of the three regions of the gene. ________ ______________________________________________________ 15. What information do chromosomes contain? Part 4: Review the roles of genes, chromosomes and proteins in protein synthesis. http://learn.genetics.utah.edu/units/basics/tour/ Click on “What is a gene?” at the top and go through the animation. Answer the questions. ________________________ ______________________________________________________ 22. What is the function of the protein hemoglobin? 23. How is sickle-cell anemia caused? ___________________________________________ ______________________________________________________ 24. What are some other proteins that genes code for? _______________________ ______________________________________________________ Click on “What is a chromosome?” at the top and go through the animation. Answer the questions. ______________________ 26. How is DNA packaged to fit into the small space of a cell nucleus? ____________ _____________________________________________________ 27. How many chromosomes are in a human cell? _________________________ 28. Why are there “pairs” of chromosomes? Where do they come from? ___________ ______________________________________________________ 25. How long would the DNA in one human cell be?
