Genetic engineering- production of human insulin

Hi,







Watch these videos on how genetically modified E. coli bacterium is produced by scientists. The human gene that controls the production of the hormone insulin was identified. it is the "cut" out from the human chromosome on which it is found and then inserted into the bacterial DNA (plasmid). This GMO is then grown on an industrial scale to produce insulin. The hormone is excreted by the GMO and the medium is collected, the cells filtered and removed. The filtrate is purified and crystalline insulin is collected and sold on a commercial scale by pharmaceutical companies.

However many people are uncomfortable in consuming GM food or using GM products. Here is another video that explores this aspect of genetic engineering.





Cheers
