Locus Description: HS4.75 polymorphic Alu element belongs to the young (Ya5) subfamily of human-specific Alu repeats. It is located on chromosome 3. DNA sequence analysis revealed that it has a long 3'-oligo-dA-rich tail (comprised of nucleotids other than A's), a low level of random mutation, and was flanked by short precise direct repeats of 17 nucleotides in length.
AAAAAAAGAATGAGATC [ALU] (A)27G AAAAAAAGAATGAGATC shows the flanking nucleotide sequences of HS4.75. 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.
