One source date November 2009 An Intergenicregion IGR is a stretch of DNA sequences located between Gene cluster clusters of gene s that contain few or no genes. Occasionally some intergenic DNA acts to control genes nearby, but most of it has no currently known function. It is one of the DNA sequence s collectively referred to as junk DNA , though it is only one phenomenon labeled such and in scientific studies today, the term is less used. In humans, intergenic regions comprise a large percentage of the genome . This could also be where noncoding RNA s are located. Though little is known about them, they are thought to have regulatory functions. Inter genic regions are different from intra genic regions or introns , which are short, non coding regions that are found within genes, especially within the genes of eukaryotic organisms. Scientists have now artificially synthesized proteins from intergenic regions. ref http www.jbioleng.org content 3 1 2 ref File Intergenic DNA.gif See also Exon Noncoding DNA Promoter biology References reflist Citation style date March 2012 Category DNA genetics stub zh ... more details
Orphan date April 2012 RRNA Ribosomal RNA rRNA intergenic spacer analysis RISA is a method of microbial community analysis that provides a means of comparing differing environments or treatment impacts without the bias imposed by culture dependent approaches. This type of analysis is often referred to as Community Fingerprinting community fingerprinting . RISA involves PCR amplification of a region of the rRNA gene operon between the small 16S and large 23S subunits called the intergenic spacer intergenic spacer region ISR. By using Oligonucleotide oligonucleotide primers targeted to conserved regions in the 16S and 23S genes, RISA fragments can be generated from most of the dominant bacteria in an environmental sample. While the majority of the rRNA operon serves a structural function, portions of the 16S 23S intergenicregion can encode Transfer RNA tRNAs depending on the bacterial species. However the taxonomic value of the ISR lies in the significant heterogeneity in both length and nucleotide sequence. In RISA, we attempt to exploit the length heterogeneity of the ISR, which has been shown to range between 150 and 1500 bp with the majority of the ISR lengths being between 150 and 500 bp. The resulting PCR product will be a mixture of fragments contributed by several dominant community members. This product is electrophoresed in a polyacrylamide gel , and the DNA is visualized following staining. The result is a complex banding pattern that provides a community specific profile, with each DNA band corresponding to a bacterial population on the original assemblage.
