## Bio::SiRNA - Designing siRNA.

This class implements the selection rules described by Kumiko Ui-Tei et al. (2004) and Reynolds et al. (2004).

## Example

     seq = Bio::Sequence::NA.new(ARGF.read)

     sirna = Bio::SiRNA.new(seq)
     pairs = sirna.design

     pairs.each do |pair|
       puts pair.report
       shrna = Bio::SiRNA::ShRNA.new(pair)
       shrna.design
       puts shrna.report

       puts shrna.top_strand.dna
       puts shrna.bottom_strand.dna
     end
