siRNAs are generally characterized by their short length (21–26 nt), 2 nt, 3′ overhanging ends, and 5′ phosphate groups. The most efficient silencing is obtained with siRNA duplexes composed of 21-nt sense and 21-nt antisense strands, paired in a manner to have a 2-nt 3' overhang (see [http://www.rockefeller.edu/labheads/tuschl/sirna.html the Tuschl lab's guide] for designing siRNAs)<ref>Functional anatomy of siRNAs for mediating efficient RNAi in Drosophila melanogaster embryo lysate., Elbashir SM, Martinez J, Patkaniowska A, Lendeckel W, Tuschl T, EMBO J. 2001 Dec 3;20(23):6877-88.
