What is the circular ring of DNA in bacterial cells called used in genetic engineering? - Plasmid, Give an example of a medical product produced using genetic engineering? - Insulin or growth hormone, State an advantage of genetic engineering in the mass production of a desired protein? - Bacteria reproduce quickly so lots of the desired protein can be produced quickly., Describe the stages of genetic engineering. Mark incorrect if you forgot any key points. - 1 - Desired gene is located in the chromosome of the human cell nucleus, this is extracted using an enzyme, a bacterial plasmid is removed from a bacterial cell and a section cut out using an enzyme, the desired gene is then inserted into the plasmid and sealed using an enzyme, the genetically modified plasmid is inserted into a host bacterial cell which is allowed to multiply many times producing many bacteria with the desired gene making the desired protein. This can then be extracted and used medically. ,
