Atomic Force Microscope image showing pRNA as single strands folded into

Self-assembled pRNA

Atomic Force Microscope image showing pRNA as single strands folded into "checkmark" shapes (a), sets of two strands that form rod shapes (B), sets of three strands that form triangle shapes (C) and multi-strand arrays forming bundles (D). The figures in the insets help illustrate how the RNA molecules in each shape are bonded to each other.
