What does it mean for an RNA structure to be "nested"?
I read that the base pairing in pseudoknots is not well nested, but ignore what nested is.

Figure 1: a-c, a single stem, two nested stems, and a pair of pseudoknotted stems shown as stem-loop diagrams. d-f, the same structures shown as dome plots

OMG Thank you so much!
