Genetic Engineering

Recap Draw a simple bacterial cell How is DNA packaged in a bacterial cell?

Genetic Engineering Genetic information can be transferred from one cell to another cell naturally. Virus injecting DNA into a cell Bacterial cells exchanging genetic information

Genetic Engineering Bacterial cells are much smaller than animal cells. They have no nucleus Their genetic information is in the form of one circular chromosome. They also have smaller plasmids which carry genes.

Bacterium

Genetic Engineering The development of Genetic engineering makes it possible to put genes from one organism into a different organism. A good example is putting human genes into bacteria. The bacteria then have the instructions to make whatever the gene is supposed to code for.

Genetic Engineering Genetic engineering has been carried out with the gene for insulin production. Insulin is a protein which we produce to control our blood sugar concentration. Some people can’t make insulin so can’t control their blood sugar concentration and therefore suffer from diabetes.

Genetic Engineering The insulin needed for diabetics can now be made by bacterial cells. This is done by inserting the human insulin gene into bacteria and they can then produce large quantities of insulin for us very quickly.
