Presentation Transcript

  1. Happy Hump-day • Bellwork: Pull out any Vocabulary materials you need to study and do so...now! 

  2. In Class Review for Test 4 DNA

  3. TEST REVIEW RULES • Pull out a few sheets of paper or a notebook • You will be grouped by tables for this activity • Your table will rotate to a new table every three minutes. (table one moves to table two, table two moves to table three, table seven moves to table one and so on) • While at your station your challenge will be to write down and try to answer as many of the questions as possible with your group before time is up. • If you don’t know the answer use your notes or HEY…flip the page over 

  4. Where does the process of Translation occur in the cell?

  5. Answer: • The process of translation occurs in the ribosome of the cell.

  6. Name the process in which mRNA is made and where it occurs.

  7. Answer: • Transcription • Occurs in the nucleus of the cell.

  8. What are the four nitrogenous bases found in RNA?

  9. Answer: • Adenine, Uracil, Cytosine, Guanine

  10. Would you see the following sequence in DNA or RNA? Why? • ACC GGC CAC GCG AAC AGA UAG GGC CAG

  11. Answer: • RNA • The sequence contains uracil at the 7thcodon

  12. What is the sugar found in the RNA nucleotide?

  13. Answer: • Ribose

  14. Which nitrogenous bases pair together in RNA?

  15. Answer: • Adenine Uracil • Thymine Adenine • Cytosine Guanine

  16. Examine the two mRNA sequences. Has a mutation occured? How do you know? • AUG CGA GGG CUA AAA CAG UAC • AUG CGA GGG CCA AAA CAG UAC

  17. Answer: • Yes a point mutation (substitution of a base) has occurred at the fourth codon.

  18. What is a codon and what does it do?

  19. Answer: • A 3 nucleotide sequence of mRNA that “tells” tRNA what amino acid to bring to the ribosome

  20. GET YOUR CODE ON!! What amino acids will be obtained from the following codons: AUG CAG UUU GGC

  21. Answer: • AUG will give you methionine • CAG will give you glutamine • UUU will give you phenylalanine • GGC will give you glycine

  22. What is a polypeptide?

  23. Answer: • The polymer of a protein. It is composed of many amino acids linked together.

  24. What is a mutation?

  25. Answer: • A mutation is a change in genetic material that results from a mistake in the replication process • Can also be caused by environmental factors

  26. What are the monomers for a carbohydrate, lipid, and protein. • Which one contains Nitrogen?

  27. Answer: • The monomer of a______ is a _________ • Carbohydrate Monosaccharide • Lipid Fatty Acid • Protein Amino Acid • Only the Protein contains Nitrogen (N).

  28. Where are proteins produced in the cell?

  29. Answer: • In the ribosome

  30. How many different substrates can fit with one enzyme?

  31. Answer: • Only one. They are very specific.

  32. What is a cell membranemainly composed of? (it’s a bio-molecule)

  33. Answer: • The cell membrane is mostly composed (made up of) LIPIDS

  34. How is a prokaryotic cell different from a eukaryotic cell?

  35. Answer: • Prokaryotic cells do not contain a nucleus or membrane bound organelles. • They carry their DNA in the cytoplasm while Eukaryotic cells carry their DNA in the nucleus.

  36. Give one example of a prokaryotic organism.

  37. Answer: • Bacteria

  38. Give one example of a eukaryotic organism.

  39. Answer: • Plants, Animals, Fungi…..basically any living thing is a Eukaryotic organism except for Bacteria.
