Key Info
  • Genetic modification of papaya
  • Duration: 04:59
  • Liz Bonnin from the BBC One series 'Bang Goes The Theory' visits Hawaii to explain how the papaya has been genetically modified on two separate occasions. The first was to overcome the Ring Spot Virus. To do this, scientists used a gun to literally fire pellets containing the viral DNA into plant cells, they then became resistant. More recently the papaya has become infected by a fungus. Genes from grape plants, which are resistant to this fungus, have been inserted into papaya plants using a bacterium as vector. First broadcast on BBC One on 'Bang Goes the Theory' in April 2011.

Ideas for use in class
  • Could be used to explain the process of genetic modification. Students could be asked to explain how the technology has changed in the last 25 years. They could then design their own genetically modified animal or plant. This clip accompanies a BBC Teachers' Pack to support Series 3 and 4 of 'Bang Goes The Theory'. The pack can be downloaded from bbc.co.uk/schools/teachers/bang/
