Drosophila Melanogaster is a fruit fly, a small insect nearly 3mms, of the class that accumulates around spoiled fruit. Fruit flies are also one of most valuable of organisms in the biological investigation, particularly in genetics and Biology of development. Drosophila almost has been used like organism model for the investigation by a century, and today, vario thousand scientists are working in many diverse aspects of the fruit fly.
The part of the work of the people on the fruit fly is historical – as much it is known already and well-understood that it is easy to direct and – and the part of the fruit fly is practical: it is a small animal, with a short vital cycle of hardly two weeks, and is cheap and easy to keep great numbers. Its importance for the human health was recognized by the concession of the 1995 Nobel prize in medicine/physiology Ed Lewis, Christiane Nusslein-Volhard and Eric Wieschaus.
The investigation of drosophila fruit flies is so popular, it would be almost impossible to enumerate the number of the things that relate to fruit flies. Originally, the fruit fly was used mainly in genetics, for example to discover that the genes were related to proteins and to study the rules of the genetic inheritance. More recently, it is used mainly in Biology, watching to see how a complex organism appears out of a relatively simple fertilized egg. The embryonic development is where the majority of the attention is concentrated, but is also interesting how much the several structures of the adult fruit fly become centered on everything in the development of composed eyes, but also in the wings, the legs and other organs.
The mutant fruit flies with defects in various genes are available, and the whole genome has been ordered recently. The vital cycle of drosophila the egg of drosophila is one half of a millimeter. Taking near a day after fertilization so that the embryo becomes a worm-like larva. The fruit fly larva eats and grows continuously, changing a day, two days, and four days after hatching. After two days like third fruit fly larva to urge, dumb a plus time to form crisálidas immovable. During the four next days, the body remodels totally to become the adult the form with wings, and are fertile in approximately 12 hours (the synchronization is for 25°C; in 18°, the development takes twice as long.)
