    PERL sequencing :Help needed.......?

    ......or code/algorithm will be appreciated. Overview: Obtain a dna FASTA sequence and randomly shuffle the sequence while maintaining the overall distribution of bases. Randomly shuffle the sequence 10-20 times, i.e. randomly select a number greater than 10 but less than 20 and then proceed to...
