Presentation Transcript

  1. How does a leopard get its spots?

  2. How do we get from genotype to phenotype? Genotype - Phenotype -

  3. Cell Differentiation When cells in different places behave differently.

  4. How can genes cause cell differentiation?

  5. Rules for the game - no moving - no using your location - no talking - you may pass cards (proteins) - you may stand up or sit down (black or yellow cell color) - one student starts with all the proteins GOAL:make a leopard spot.

  6. A simple rule for cell differentiation 1. One cell starts with many proteins 2. Each cell passes the proteins it has to its neighbors at random. 3. Cells start as black 4. After a set periods of time, cells with enough proteins turn yellow. What does this look like?

  7. Morphogen A chemical (such as a protein) used as a message during cell differentiation.

  8. How can a computer help us?

  9. Requirements for complex patterns - Two morphogens - The morphogens can interact.

  10. Patterns from two morphogens
