Figure 1From: Naturally occurring variations in sequence length creates microRNA isoforms that differ in argonaute effector complex specificityTwo mature micro(mi)RNA sequences derived from the ath-MIR156h pre-miRNA hairpin. The primary hairpin ath-MIR156h gives rise to two mature isoforms of ath-MIR156h, which differ by one nucleotide on the 5' terminus.Back to article page
