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.
DVD-Video is a consumer video format used to store digital video on DVD discs, and as of 2003 is the dominant consumer video format in Asia, North America, Europe, and Australia. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e. g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below).
