Presentation Transcript

  1. Monday, March 26, 2012 RNA checkup on Block Day

  2. Label: mitochondria, chloroplasts, vacuole, nucleus, DNA Elodea leaf cell human cheek cell mitochondria chloroplasts vacuole nucleus (DNA here) (DNA here) cytoplasm

  3. Where is protein made in a cell?

  4. DNA does not leave the nucleus of eukaryotic cells... but proteins are made outside of the nucleus by ribosomes ribosomes (proteins made here) (proteins made here) nucleus (DNA here) (DNA here)

  5. DNA and ribosomes are at different locations in a prokaryotic cell. E. coli bacteria cell ribosomes Ribosomes make protein but are not in the same location as DNA in a cell. How can the proteins be made according to the DNA information? (proteins made here) DNA

  6. Information flow from DNA to trait Observed trait DNA protein Made by ribosomes outside of nucleus Stored in nucleus

  7. messenger RNA • mRNA transfers information from the DNA in the nucleus to the ribosomes. • Ribosomes build proteins according to the mRNA information received.

  8. Information flow from DNA to trait messenger RNA Observed trait DNA protein Made by ribosomes outside of nucleus Stored in nucleus Transcriptionis the process used to convert DNA information into mRNA information. Note: DNA does not become RNA; the information in DNA is copied as RNA

  9. Some things we will learn… • Where is protein made in a cell? • How does the information stored in DNA determine which proteins can be made in a cell? • How is protein made in a cell? • How does the environment influence which proteins are made in cell?

  10. that codes for a specific trait/protein. Gene: one section of the DNA AG T A C G T A G TC A G G T T T C A T G C A T C AG T C C A A Trait/Protein

  11. Make an entry- Entry 27: Same DNA/Different Protein-3/26/12 Gene Coding sequence for a protein

  12. Show transcription video clip

  13. RNA Polymerase Activator Transcription factor

  14. Show animation of transcription PPT

  15. Activator folds over and touches enzyme which is the signal to begin transcription. RNA polymerase (enzyme) reads the gene and matches RNA nucleotides to create a mRNA strand that will code for that protein.

  16. Show without activator PPT

  17. How can cells have the same DNA but different proteins? Answer in your own words on the sticky note.
