Locus Description: HS2.25 polymorphic Alu element belongs to the young (Ya5/8) subfamily of human-specfic Alu repeats. It is located on chromosome 13. DNA sequence analysis revealed that it has a long 3'-oligo-dA-rich tail (41 nucleotides in length), a low level of random mutation, and was flanked by short precise direct repeats of 8 nucleotides in length.
ATTCACCA [ALU] (A)₄₁ ATTCACCA shows the flanking nucleotide sequences of HS2.25. The composition of the 3' oligo (dA) tail is denoted by the appropriate nucleotide in parenthesis followed by the length in subscripts. The nucleotide sequences comprising the flanking direct repeats of each Alu element are in bold.
