Short Interspersed Nucleotide Elements (SINEs)

    Short Interspersed Nucleotide Element (SINE) repeats are several hundred basepairs in length and distributed throughout the genome, including within the introns between the exons of protein-coding gene regions. In humans, the Alu repeat family consists of 200~300bp elements repeated several hundred thousands of times.
