  1. Bioengineering War Heads.

  2. Cloning: • Cloning is the process in which you manipulate nature to duplicate it.

  3. history In the late 1800s a scientist named Hans Driesch started to experiment on cloning. He did this not to get identical products but to prove that genetic material isn’t lost during cell division. • In 1902 Hans Spemann started to clone on salamanders. Since their cells are so small he had to use his sons hair as a knife to separate the cells. • In 1977 German scientist had succeeded in cloning three mice. Since the cells are so small other scientist didn’t believe that he had accomplished that experiment, so they challenged to redo it. They went through his lab and found embryos in a cabinet, when they saw that they where all at different stages they didn’t believe his success. • July 5th 1996, the first cloned lamb was born. Dolly the sheep who was cloned took 277 attempts to create and hasn’t been able to recreate. It took a year to make sure her DNA was the same as the frozen mammary cells.

  4. 5 benefits • It might be able to reverse aging. • Clone important organs for transplants. • It might replace your defective genes. • For women who go through infertility it can be possible for couples to have children. • It can help scientist come up with a cure for cancer.

  5. 5 risks/flaws • Telemetric differences . • Abnormal gene expression patterns. • Problems during later development. • There is a high failure rate. • Clones may die off easily if not under good conditions.

  6. 5 examples • Dolly the cloned sheep. • Transgenic mice. • Monoclonal antibody production. • Cloning a YAC. • Reproducing things

  7. Future of cloning • Human genes may be introduced into other organisms. • Transgenic animals may produce human proteins. • Ex.) pigs and sheep they would become “Drug factories” • They would be able to produce human proteins in its milk and insulin, used to treat diabetes.

  8. Ethical issues • Cloning is unnatural self-engineering. • Will failures, such as deformed. • Clone may not be accepted. • The risks to the first person. • Clone may die.

  9. Your opinion We think that cloning has its benefits but also major issues. Scientist should keep performing experiments to add information to their research. Then maybe some day we will be able to clone humans.
