sidebarA. Genetic engineering (GE) is the modification of an organismâs genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species.hen gene transfer occurs, the resulting organism is called transgenic or a GMO (genetically modified organism). Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species.
Short for high definition-DVD, a generic term for the technology of recording high-definition video on a DVD. In general, HD-DVD is capable of storing between two and four times as much data as standard DVD. The two most prominent competing technologies are Blu-ray and AOD.
A Blu-ray disc is a form of optical disc. It looks the same as a DVD, but can store about six times as much information as a standard DVD. Because they can hold so much more information, Blu-ray discs can provide high-definition audio and video for output on HD TVs and surround sound systems, while an ordinary DVD cannot.
