1.5 genetic engineering

• genetic engineering


  transfer of genetic information from 1 organism to another

  
• step 1 of genetic engineering

  identify section of dna that has the needed gene from a source chromosome

  
• step 2 of genetic engineering

  extract required gene

  
• step 3 of genetic engineering

  extract plasmid from required bacterial cell by using enzymes to cut the plasmid

  
• step 4 of genetic engineering

  insert required gene into bacterial plasmid so they can fuse

  
• step 5 of genetic engineering

  insert plasmid into host cell to make genetically modified organism

  
• insulin


  example of genetically modified product, prior to gm insulin was from animals, causing reactions and straining the supply
