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

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

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.


Genetic engineering and biotechnology

  • 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.
