Duplicating Genes The building block of genetic

Extracting DNA

• Restriction enzyme
• has a specific shape
• travel along the channels of the double helix
• Scan for a certain sequence of amino acids.
• When the desired trait (sequence of amino acids)
  is found, it cuts the DNA
• The new DNA can now be implanted into the cut
  bacteria plasmid

Duplication

• The restriction enzyme leaves an adhesive end
• - helps the new gene to
  attach
• DNA strip and plasmid are fused together.
• -Ligase enzyme
• Bacteria then reproduce
• Bacteria also manufacture the enzyme needed to
  cut the desired string of DNA
• desired product the gene are produced

Practical Uses

• Duplication of genes for implantation
• -Agricultural animals
• -make animals
  more efficient and
  beneficial for human use and
  consumption
