MicroRNAs (miRNAs) are an abundant class of ∼22-nucleotide (nt) noncoding RNAs, some of which are known to control the expression of other genes at the posttranscriptional level (1–41). We developed a computational procedure (MiRscan) to identify miRNA genes (52) and apply it here to
Lim et al. (2003) studied this question.
