Presentation Transcript

  1. BiotechnologyBreakthroughs: Cloning Biojudiciary Project http://www.biojudiciary.org Toby M Horn, PhD, Carnegie Institution of Washington

  2. Life Tools • Cells • DNA • Enzymes

  3. Cells A multicellular organism starts from a single cell -the fertilized egg -that divides into cells that continue to divide and/or differentiate.

  4. Cell Clones Single bacteria, yeast, animal and plant cells can form clones -- colonies of identical cells – in cell culture. • http://www.mcb.harvard.edu/hastings/Images/bacteria.gif

  5. DNA DNA forms a double-stranded helix through H-bonds between the complementary bases (A-T, G-C) on each strand. Adapted from: http://www.ncbi.nlm.nih.gov/books/bv.fcgi?call=bv.View..ShowSection&rid=cell.figgrp.1404

  6. Enzymes Enzymes cut DNA at specific sequences. Enzymes re-seal the strands. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Search&db=books&doptcmdl=GenBookHL&term= DNA+molecules+AND+cooper%5Bbook%5D+AND+165201%5Buid%5D&rid=cooper.figgrp.455

  7. Types of Clones • Natural • Managed • Molecular • Nuclear • Stem Cell

  8. Natural Clones

  9. Managed Clones (grafts, pure cultures, micropropagation)

  10. Molecular Clone(recombinant DNA)

  11. Nuclear Transplant

  12. Stem Cell Clone

  13. The Biojudiciary Project Like all new technologies, the biotechnologies illustrated here -- and others --- raise significant ethical, legal and policy issues that must be given serious attention and properly addressed in an open manner. http://www.biojudiciary.org
