4/24/15 – Second Posting (with updates)

AP BIO

  • Remember the AP Bio test is rapidly approaching. You should be reviewing daily.
  • HW:
    • Due Monday: Finish the Protein synthesis lab. Here’s a link to the packet, make sure you complete the questions on page 11. You’ll also need a codon chart to complete this packet, so make sure you either have one or just google it. Make sure you also review the process of transcription and translation. Your book does a good job of explaining it but there are a quadrillion videos and animations of it out there.
    • Due Monday: Read/outline the following topics and watch the vids.
      • Chapter 16:
        • DNA history, important experiments that led to the understanding of DNA as the heritable material. DNA Part 1 and DNA Part 2
        • DNA replication. Here’s a Bozeman vid
        • You have to draw cartoons/diagrams/flow charts for this chapter. You can stare at it for a hundred years but won’t really get it until you draw the diagrams.
    • Due Tuesday:
      • Read and outline selections from chapters 18 and 19.
        • Compare and contrast gene regulation between prokaryotes and eukaroytes.
        • How genetic recombination/variation occurs in viruses and bacteria
        • Insertion sequences and transposons
        • How bacteria copy their chromosomes
        • 18.4 – Operons….How bacteria regulate gene expression  – I can’t adequately express the importance of this topic.
          • inducible vs. repressible operons
        • Eukaryotic gene regulation.
          • Good figs  to review/study: 19.3, 19.5, 19.8, 19.9, 19.12 ( a good cell communcation/signaling example)
          • Topics:
            • regulation of gene expression (figs 19.3 and 19.5 deals with this best)
            • rna processsing, mRNA degradation
            • cancer, regulation of cell cycle, p53, p21 genes
            • transposable elements.
  • Here’s the google survey for the evening practice test.

AP BIO

  • HW (for tomorrow): Chapter 17 outline (we’re skipping chapter 16 for now, we’ll come back to it
    • 17.1: Principles of transcription & translation, the genetic code, fig 17.3 and 17.4,
      • how genes are expressed
      • how DNA is coded into mRNA, then mRNA is read by ribosomes and polypeptide chains are synthesized
    • 17.2: Transcription: how genes are “switched on” and mRNA is transcribed
      • terms to review/study: RNA polymerase, promoters, terminators, transcriptional unit, transcription factors.
      • fig 17.8 is a good one to look at (and/or draw).
      • in general, what you should know is how transcription is initiated and terminated.
    • 17.3: Processing of mRNA after it’s transcribed
      • figs 17.9, 17.10, 17.11
      • General overview of how rna is processed, how introns are “cut” out of the transcript, and how exons are “spliced” back together.
        • know the role of snRPs (pronounced “snurps”) and ribozymes, especially “Spliceosomes” in this process.
      • Introns aren’t just “junk”….be able to explain why.
    • 17.4: Translation.
      • know the roles and importance of the molecular components involved in translation:
        • Ribosomes (the role and structure of)
        • mRNA
        • tRNA
        • amino acids
  • Complete the remainder of chapter 17 by Friday.

AP BIO

  • HW – Due Monday
    • Watch this vid on  genetic recombination and gene mapping. You’ll need it for the practice problems.
    •  Chapter 15 practice problems: 1, 2, 3, 5, 6 20, 24. There’s also an example for questions 5 and 6 in your book, in fig 15.6.
    • Make sure you review vocabs and terminology from both chapters 14 and 15.
  • The Quiz Bowl/Review has been moved to April 30th, 9th period. Please let me know if you’ll attend.

HONORS BIO

  • HW: If you didn’t finish the last practice problem during class, finish for homework:
    • Dihybrid cross (look it up in 11.3):
      • In pea plants, the green color allele (G) is dominant over yellow color allele (g) for seed color and tall (T) is the dominant allele in plant height. Parents heterozygous for both traits are cross-pollinated.
        •  Make a 4 x 4 Punnett square.
        • Determine the phenotypic ratios for the four different phenotypes of offspring.

AP BIO

  • Lab packets are due tomorrow.
    • M&M lab – make sure you have all the class data and complete the chi-square test. Here’s the class data.
    • Onion Root Tip Lab: Complete the lab packet, but also run a chi-square analysis on the class data. The class data spreadsheet contains the proportion of cellsexpected to be in each phase.
      • To the one students who asked me about the chicken cell section of the lab….I made a mistake. You do need to do complete that part of the lab, but you already have that data in the table.
