Predicting RNA structure and function requires understanding its dynamic folding pathways. New data mining and visualization tools aid in analyzing RNA folding, revealing intermediate and final conformations for better gene expression insights.

Area of Science:

  • Computational Biology
  • Molecular Biology
  • Bioinformatics

Background:

  • RNA molecules adopt multiple conformations, not always the lowest energy state, impacting function.
  • RNA folding occurs dynamically during transcription and can involve transitions between functional states.
  • Understanding these dynamic behaviors is crucial for predicting RNA structure and function.

Purpose of the Study:

  • To develop and present data mining techniques and interactive visualization tools for analyzing RNA folding pathways.
  • To aid in the prediction of RNA secondary structure and its associated biological functions.
  • To address the challenges of simulating dynamic RNA behavior and interpreting complex folding data.

Main Methods:

  • Development of data mining techniques integrated with interactive visualization.
