genetic engineering 4 4 7
Genetic Engineering 4.4.7
  • Genetic engineering: the deliberate manipulation of genetic material.
  • Genetic code: The sequence of nucleotides in DNA or RNA that determines the specific amino acid sequence in the synthesis of proteins.

Genetic Engineering
  • It is possible to move material between species because the genetic code is universal.
  • The transfer of genetic code can cause genetic mutations in animals
gene transfer 4 4 8
Gene Transfer 4.4.8
  • Gene transfer: Involves the use of plasmids, host cell (bacterium, yeast, or other cell), restriction enzymes (endonucleases), DNA ligase.
  • Gene therapy: The treatment of certain diseases by introducing specific engineered genes in a patients cells.
  • Vector: Is what is needed to carry the gene into the host cell; plasmids are often used as vectors.
  • Restriction enzyme: Used to cut a desired section of the DNA.
  • Plasmids: Used to clone a desired gene.
  • Host cell: The cell used to receive the genetic material.

The use of gene transfer for diabetics
  • A human gene that codes for insulin can be inserted into a plasmid and then inserted into a host cell (bacterium). The bacterium then synthesis insulin which can then be collected and used by diabetics.

Note- Gene transfer involves the following elements: a vector, a host cell, restriction enzyme, DNA ligase.

  • Step 1: Introduce the desired gene into a plasmid and transfer it into a bacterial cell, then culture the bacteria.
    • Note: many of the bacteria will have a plasmid with the desired gene
  • Step 2: Use restriction enzymes to cut the desired gene out of the plasmids and purify the gene using gel electrophoresis.
