The human genome contains an estimated 100,000 truncated and 4,000 full-length LINE-1 elements. [10] Due to the accumulation of random mutations, the sequence of many LINEs has degenerated to the extent that they are no longer transcribed or translated. Comparisons of LINE DNA sequences can be used to date transposon insertions in the genome.
LINE1 (an abbreviation of Long interspersed nuclear element-1, also known as L1 and LINE-1) is a family of related class I transposable elements in the DNA of many groups of eukaryotes, including animals and plants, classified with the long interspersed nuclear elements (LINEs). [1]
For example, the 5' of the Alu SINE is derived from 7SL RNA, a sequence transcribed by RNA Polymerase III, giving rise to the RNA element of SRP, an abundant ribonucleoprotein. [6] 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 ...
