| All genes have regulatory regions in addition to regions that explicitly code for a protein or RNA product.replica rolex watches A regulatory region shared by almost all genes is known as the promoter, which provides a position that is recognized by the transcription machinery when a gene is about to be transcribed and expressed. A gene can have more than one promoter, resulting in RNAs that differ in how far they extend in the 5' end.[4] Although promoter regions have a consensus sequence that is the most common sequence at this position, some genes have "strong" promoters that bind the transcription machinery well, and others have "weak" promoters that bind poorly. These weak promoters usually permit a lower rate of transcription than the strong promoters, because the transcription machinery binds to them and initiates transcription less frequently. Other possible regulatory regions include enhancers,air max 90 which can compensate for a weak promoter. Most regulatory regions are "upstream"—that is, before or toward the 5' end of the transcription initiation site. Eukaryotic promoter regions are much more complex and difficult to identify than prokaryotic promoters.
In Indonesia, depending on the principles they are administered, villages are called desa or kelurahan. A desa (a term that derives from a Sanskrit word meaning "country" that is found in a name such as "Bangladesh") is administered according to traditions and customary law (adat),nike air chaussures, while a kelurahan is administered along more "modern" principles. Desa are generally located in rural areas while kelurahan are generally urban subdivisions. A village head is respectively called kepala desa or lurah. Both are elected by the local community. A desa or kelurahan is itself the subdivision of a kecamatan (district), in turn the subdivision of a kabupaten (regency). In urban areas of the Philippines, the term "village" most commonly refers to private subdivisions, especially gated communities. These villages emerged in the mid-20th century and were initially the domain of elite urban dwellers. Now they are now common in Metro Manila and other major cities in the country and their residents have a wide range of income levels. Such villages may or may not correspond to administrative units (usually barangays) and/or be privately administered.ed hardy clothing Well-known villages in Metro Manila include Forbes Park and Dasmari?as Village. Barangays more correspond to the villages of old times, and the chairman (formerly a village datu) now settles intrapersonal matters or polices the village, though with much less authority and respect than in Indonesia or Malaysia. |
