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.
HD-DVD (high-density DVD) is an optical digital storage medium with a capacity that far exceeds that of standard DVD media. There are two types. The single-layer HD-DVD offers up to 15 gigabytes (GB) of storage capacity, and the double-layer HD-DVD offers up to 30 GB. A double-layer HD-DVD can contain up to eight hours of 1125-line high-density television (HDTV) programming, or up to 48 hours of standard-definition television programming.
