  1. Unit 2 Test Review StationsDNA – RNA – Protein Synthesis

  2. Bell Work • Pick up the task card review sheet • Turn in your hippogriff protein synthesis • Get out your web quest and notes REMINDER: Test Tomorrow over DNA, RNA and Protein Synthesis

  3. Nucleotide Card #1 Identify each part of the nucleotide above: • What is the circle? • What is the pentagon? • What is the rectangle?

  4. Card #2 What is the difference between a purine and a pyrimidine? Which bases belong in each category?

  5. Card #3 How do the bases in DNA pair? How many hydrogen bonds are found between each base pair?

  6. Card #4 What are the three biggest differences between RNA and DNA?

  7. Card #5 Label each type of RNA and list the function of each.

  8. Card #6 What are the two stages of protein synthesis and what is produced in each?

  9. Card #7 What is the correct sequence for the transfer of information?

  10. Card #8 What is the enzyme that completes transcription and what two jobs does it do?

  11. Card #9 What is the start codon? What will be the first amino acid added to every protein?

  12. Card #10 Identify each labeled component on Figure 1.1

  13. Card #11 Translate the following mRNA: CUC – AAG - UGA

  14. Card #12 Create an mRNA sequence that could code for: His – Glu - Pro

  15. Card #13 During which stage of protein synthesis will you find ALL THREE types of RNA working together?

  16. Card #14 What mechanism GUARANTEES that the tRNA adds the correct amino acid in the order specified on the mRNA?

  17. Answer Key: • Check your answers against the key to ensure you are studying the correct information

  18. Nucleotide Card #1 Phosphate Nitrogen Base Deoxyribose - Sugar

  19. Card #2 • Pyrimidines = one ring in the base structure • Thymine and Cytosine • Purines = two rings in the base structure • Adenine and Guanine

  20. Card #3 ADENINE THYMINE GUANINE CYTOSINE Guanine pairs with Cytosine and they have 3 hydrogen bonds Adenine pairs with Thymine and they have 2 hydrogen bonds

  21. Card #4 DNA = Deoxyribose Sugar, Double Stranded and Thymine RNA = Ribose Sugar, Single Stranded and Uracil

  22. Card #5 mRNA = copies the DNA code and carries it to the ribosome rRNA = makes the ribosome tRNA = carries amino acids to the ribosome and links them into a polypeptide chain according to the code on mRNA

  23. Card #6 Transcription = mRNA Translation = protein

  24. Card #7 DNA – RNA – PROTEIN

  25. Card #8 RNA Polymerase = unzips DNA and copies the code to create mRNA

  26. Card #9 AUG = MET

  27. Card #10 A = NUCLEUS B = MRNA C = RIBOSOME D = TRNA E = ANTI-CODON F = CODON G = MRNA

  28. Card #11 Translate the following mRNA: CUC – AAG – UGA LEU – LYS - STOP

  29. Card #12 Create an mRNA sequence that could code for: His – Glu – Pro CAU OR CAC GAA OR GAG CCU, CCA, CCG, CCC

  30. Card #13 During which stage of protein synthesis will you find ALL THREE types of RNA working together? TRANSLATION

  31. Card #14 What mechanism GUARANTEES that the tRNA adds the correct amino acid in the order specified on the mRNA? The interaction between tRNA anti-codons and the mRNA codons – an anti-codon can only bind ONE mRNA codon
