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.
HUMULIN 70/30 (70% human insulin isophane suspension and 30% human insulin injection [rDNA origin]) is a human insulin suspension. Human insulin is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli.
