Presentation Transcript

  1. We compare DNA to an encyplopedia (DNA = ) that may not leave the public library. • How do you get the information out of the library? • Accordingly, what needs to happen for using genetic information in the cytoplasm?

  2. Making a protein is like reading a library book.  --------- --------- --------- --------- Cell Neighborhood Cytoplasm Nucleus Library Home ? DNA ? Home-work New Protein

  3. Using the information encoded in the DNA: Producing Proteins! = “Protein Synthesis” = “Gene Expression”

  4. Gene Expression From the DNA Code to the amino-acid sequence of a Protein Building the De-Coding Machine

  5. Making a protein is like reading a library book.  --------- --------- --------- --------- Cell Neighborhood Nucleus --------- --------- --------- --------- Library DNA Home-work --------- --------- --------- ---------

  6. Central Dogma of Molecular Biology: Information Flows in One Direction: DNA RNA Proteins. Transcription (Nucleus) Translation (Cytoplasm)

  7. Transcription: A modified copy of the DNA A. Keeping the DNA ‘encyclopedia’ safe in the nucleus. B. Copying only the necessary information (‘pages’). C. Only when the information is required.

  8. The Transcript: RNA Compare Transcription to replication.. lPsCIECNE dna rEPLICATION Transcription Translation Lewport RNA Transcription - from promoter to terminator RNA Transcription - from promoter to terminator

  9. DNA and RNA Compare DNA to RNA:

  10. Making a protein is like reading a library book.  DNA = cytoplasm nucleus
