sequences:GCGCUUCGCCGCGCGCG&GCGCUUCGCCGCGCGCGHere the two monomer curves are superpositioned (red dashed line), so only one line is visible. In this example, at a concentration of about 0.5 mmol 50% of the molecule is still in monomer form. The startup concentration for monomeres here is 1 each (2 in sum).
