Genetic Engineering

• Stage 1

  1. Gene is identified on the chromosome
• Stages of genetic engineering

  • Bacterial cell
  • Gene
  • Plasmid
  • Modified plasmid
  • New host bacterial cell
  • Product
• Genetic material


  The gene
• When talking about genetic engineering always mention enzymes
• Host

  Bacterial cell
• Genetic engineering involves the transfer of genetic material from one organism to another
• Stage 4

  Plasmid is cut open using enzymes
• Stage 6

  Modified plasmid is placed into a new host bacterial cell
• Stage 3

  A plasmid is removed from a bacterial cell
• Stage 7

  Bacterial cells divide and produce the product which is then collected and purified
• Stage 5

  Gene is inserted into the plasmid using enzymes
• The gene is removed ffrom the chromosome using enzymes
