Polymorphism Description: Sb19.10 polymorphic Alu element belongs to the young (Ya8) subfamily of human-specific Alu repeats. It is located on chromosome 19. DNA sequence analysis revealed that it has a 3'-oligo-dA-rich tail (27 nucleotides in length), a low level of random mutation, and was flanked by short precise direct repeats of 15 nucleotides in length.
GAAACAGGGTCTTTG [ALU] (A)₂₇ GAAACAGGGTCTTTG shows the flanking nucleotide sequences of Sb19.10. 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.
