Analysis of potential miRNAs.

<p><b>A</b>) Size distribution of the 105 miRNAs shows a range from 22–29 nts with a peak at 26 nts. <b>B</b>) Origins of the 105 miRNAs show that the majority is derived from ORFs and unannotated regions. <b>C</b>) A Venn diagram showing the conservation of potential miRNAs among the three sequenced isolates of <i>Giardia</i>. A BLAST search resulted in 41 miRNAs only in WB, 4 miRNAs conserved between WB and GS whereas 35 shared between WB and P15. A total of 25 miRNAs are conserved among all three isolates.
