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.
6) Genetic engineering is being used to create human organs but in the long run if it can create genetically modified, perfect human specimens who are better than the creators than this may be disastrous.) Genetic engineering is meant to make food crops more resistant to disease, but the mere act of modification of the naturally selected food crops may actually disturb the delicate balance of biodiversity which exists in nature.
