Regions targeted by the 10 asRNA probes used to profile the tetrahymena gI intron ribozyme. Ten asRNA probes previously published in sowa et al. (2015) (18) were used to measure changes in regional accessibility for specific regions along the ribozyme transcript.

Probe 1	P1 (5’ end post-splicing)	Probe 5	P5c (catalytic activity)	Probe 9	P9.2 (guides folding of the core)
Probe 2	L2.1 (tertiary contact)	Probe 6	P5-a (A-rich bulge)	Probe 10	P10 (3’ end/splice site)
Probe 3	P3-J3/4 (3’ splicing/catalytic region)	Probe 7	P6b (tetraloop receptor)
Probe 4	L5b (catalytic activity)	Probe 8	L8 (intron processing)
