The alu sine

WebNov 1, 1994 · The Alu sequence is a SINE (Short INterspersed Element) that is abundant in the human genome. A new analysis (1) reveals an unexpected conservation of some bases in the DNA sequence of the element. The bases involved include those forming an RNA polymerase III promoter. Web9. Alu elements are a type of transposable element. They possess the means for their own duplication and movement. Alu is a SINE-like element that is transcribed by RNA Pol III, and so a single DNA copy can make multiple RNA copies, each capable of inserting into DNA, so it's no wonder they have a very high copy number.

WebSINE elements are copied by RNA polymerase III and rely on the presence of reverse transcriptase from other sources. The Alu element is an approximately 350-bp SINE and makes up 11% of the human genome, which makes it the most abundant feature. WebIn humans, the most abundant SINE is the ALU, named for the Alu-I restriction site occurring in these elements.

WebFor example, the 5' of the Alu sine is derived from 7SL RNA, a sequence transcribed by RNA Polymerase III which codes for the RNA element of SRP, an abundant ribonucleoprotein. The body of SINEs possess an unknown origin but often share much homology with a corresponding LINE which thus allows SINEs to parasitically co-opt endonucleases coded … WebOct 6, 2005 · Alu elements are primate-specific SINEs of ~300 bp. These elements have been extremely successful at propagating in primate genomes as evidenced by the fact that they make up ~10% of the human genome by mass [ 23, 26 ]. Distinct subfamilies of Alu elements in the human genome have been described in detail [ 17, 18, 23, 27 – 32 ].
