Background:

  • Predicting RNA secondary structure is crucial for understanding RNA function.
  • Free energy minimization is a common approach for structure prediction.
  • Computational tools are essential for analyzing complex RNA sequences.

Purpose of the Study:

  • To provide detailed protocols for RNA secondary structure prediction.
  • To introduce RNAstructure (for PCs) and mfold (for Unix) for this purpose.
  • To enable prediction of both minimum free energy and suboptimal RNA structures.

Main Methods:

  • Utilizing free energy minimization algorithms.
  • Employing the RNAstructure software package.
  • Leveraging the mfold web server for Unix-based computations.
