Hypothesis
The study investigates the sequence-structure relations of RNA pseudoknot structures and their implications for molecular evolution.
Conclusion
The results suggest that 3-noncrossing pseudoknot RNA structures are well-suited for molecular evolution, indicating the existence of extended neutral networks.
Supporting Evidence
- The study found that approximately 50% of RNA structures folded contained pseudoknots for sequences of length 100.
- The dominant pseudoknot shapes were identified based on the analysis of 2000 random sequences.
- The findings suggest that the majority of pseudoknot structures are irreducible, complicating their computation.
Takeaway
This study looks at how RNA can fold into complex shapes called pseudoknots, which are important for understanding how life evolved.
Methodology
The study uses a novel algorithm called 'cross' to predict RNA structures and analyze their statistical properties.
Limitations
The study does not provide a method for generating random pseudoknot structures with uniform probability.
