SINE (short interspersed element) Any of a class of dispersed moderately repetitive DNA found in eukaryotes, consisting of numerous copies (>105) of relatively short (<500 bp) sequences scattered throughout the genome. SINEs are not translated into proteins, occur mostly in introns, and are thought to be degenerate copies of retrotransposons, with unknown function. The most notable example in humans and other primates is the Alu family.
