Figure 2: Expansion and contraction of the primer RNA helix at
the mini-D stage. a, Extended mini-helix structure at the
mini-D stage. The simulated annealed omit maps (contoured at 3.5

for the indicated nucleosides are shown. b, Back-tracked
mini-helix structure at the mini-DC. Other stages have the same
standard helix structure.
