Honolulu technique Honolulu technique Presentation Transcript

  • Honolulu Technique By: Sydney Dudley
  • What is Cloning?• Cloning refers to the development of offspring that are genetically identical to their parent.• There are two techniques for cloning: – The Roslin Technique – The Honolulu Technique
  • Cloning 101• http://www.youtube.com/watch?v=q0B9Bn1 WW_4&safety_mode=true&persist_safety_m ode=1&safe=active View slide
  • Background• Founded in 1998 byTeruhiko Wakayama and Ryuzo Yanagimachi of the University of Hawaii• This technique has successfully cloned five generations of mice. View slide
  • Step 1• Nucleus of a cell is extracted from the organism that is being cloned – Cumulus cells are the most commonly used • Cumulus cells surround an egg cell. Egg Cumulus cell cells
  • Step 2• Nucleus is removed from an unfertilized egg cell.
  • Step 3• The nucleus from the first cell is injected into the enucleated egg cell.
  • Step 4• The new egg cell is placed into a chemical bath to jumpstart cell growth. – Chemical bath is less harmful than electric shock used in the Roslin Technique.
  • Step 5• The cells develop into embryos and are placed in a surrogate mother and carried to term.
  • Success Rate• Honolulu technique- 3 clones out of every 100 attempts.• Roslin technique- 1 clone out of every 277 attempts.
  • Uses• The Honolulu Technique can be used for: – Research of diseases such as AIDS, cancer, or diabetes – Genetically alter animals for the production of human transplant organs – NOT intended for the cloning of humans
  • Arguments Against Cloning• Scientific: – Low success rate – Clones don’t live as long – Decreases genetic diversity• Practical – Easier to produce natural offspring• Religious – Human life is precious in God’s eyes – People cloned for “spare parts” – Men should not play the role of God
