  1. 1.
  2. 2. Start of Genetic Engineering<br />Genetic engineering: Scientific alteration of DNA.<br />Started after the discovery of DNA by James Watson and Francis Crick.<br />DNA determines physical and mental characteristics.<br />
  3. 3. Types of Genetic Engineering<br />Germline Gene Therapy<br />Alteration of genome takes place in reproductive cell.<br />Alterations can be inherited if inserted into chromosomes.<br />Mostly done in animals.<br />
  4. 4. Types of Genetic Engineering<br />Somatic Cell Gene Therapy<br />Alteration of genome in other than sex cell.<br />Bad genes can be swapped for good ones.<br />Not inheritable.<br />Limited success rate.<br />
  5. 5. The down side<br />
  6. 6. Creating bigger salmon..<br />May feed more people..<br />But is it right?<br />
