Figure 2From: Evolution of MIR159/319 microRNA genes and their post-transcriptional regulatory link to siRNA pathwaysExamples of the five types of MIR159/319 precursor stem-loops. The sequences corresponding to the four conserved partitions are highlighted: red, miR; blue, miR*; green, ACR5; orange, ACR3. Notice that the conserved regions may have slight differences from the true miRNA:miRNA* duplexes.Back to article page
