genetic engineering

• what is genetic engineering?

  taking a gene from a desirable characteristic and transferring it to another organism
• what is genetic modification?


  modifying the organisms genome
• what is gene therapy?

  giving a person the healthy version of a gene
• what are the pros of genetically modified crops?

  can easily make crops with desirable characteristics

  -resistant to disease

  -increased yield

  -increased quality

  -resistance to insects
• what are the cons of genetically modified crops?

  -don’t know how they might affect our health

  -plants could outcompete other plants and change the ecosystem
• how do we transfer the gene from one organism to another?

  -isolate section of DNA from gene using enzymes

  -insert gene into vector which could be a virus or a bacterial plasmid

  -introduce vector to the organism we want to have the gene

  -they take up the vector and start producing the protein the gene codes for

  ITS VERY INTERESTING POST
• can genetic engineering only be done between two organisms of the same species?

  no
