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.
Genetic engineering is a process in which recombinant DNA (rDNA) technology is used to introduce desirable traits into organisms.A genetically engineered (GE) animal is one that contains a recombinant DNA (rDNA) construct producing a new trait.enetic engineering is a process in which recombinant DNA (rDNA) technology is used to introduce desirable traits into organisms.
