QR code is the trademark for a type of matrix barcode first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes to efficiently store data; extensions may also be used.
Next. Genetic engineering can be used to create organisms that produce large amounts of useful substances-for example, bacteria can be engineered to produce human insulin to treat diabetics. Genetic engineering can also be used to create and store DNA fingerprints, which can be used for identification purposes.
In addition to bacteria, other biotechnologists use yeast in recombinant DNA technology to make human insulin. Yeast can perform more of the complicated cellular processes that occur in human cells, making it a more useful organism for producing human substances.or more information on using the use of DNA technology in producing insulin, please visit DNA Interactive: Manipulation. Producing Genetically Modified Foods A widely debated application of recombinant DNA technology is in the production of genetically modified foods.
