Presentation Transcript

  1. Lactase genes and evolution

  2. Points of concern • Lactase and curriculum • General Biology course • General Microbiology • Genetics • What is the problem? • Students misconceptions

  3. Data set 86

  4. resources • See images.ppt and .doc files for visual database of organisms from which sequences were obtained • Sequence files (.doc) are organized by type of organism and lactase subunit

  5. Sample Questions: Level 1 • Is the bacterial lactase gene similar to the human lactase gene? • Is this gene exclusive to eukaryotic or to prokaryotic organisms? • How is this gene distributed across the organisms?

  6. Sample Questions: Level 2 • How does the bacterial lactase gene compare to archaebacteria? • What evolution scheme can be inferred? • Describe the evolutionary relationships within and among the different groups of organisms.

  7. Plant data

  8. Unrooted tree for plant data

  9. Splt Decomposition (ESTEEM module) to determine relationships between four plants based on lactase sequence
