Predicting conserved RNA secondary structures is crucial for understanding noncoding RNAs. The RNAalifold program enhances accuracy by analyzing multiple aligned sequences, considering thermodynamic stability and sequence covariation.

Area of Science:

  • Computational Biology
  • Bioinformatics
  • Molecular Biology

Background:

  • Functional RNA secondary structures are evolutionarily conserved.
  • Predicting these structures is vital for studying noncoding RNAs.
  • Comparative sequence analysis yields more accurate RNA structure predictions than single-sequence folding.

Purpose of the Study:

  • To provide a tutorial on installing and using the RNAalifold program.
  • To guide users in interpreting RNAalifold results.
  • To demonstrate RNAalifold's capability in predicting conserved RNA secondary structures.

Main Methods:

  • Utilizing the RNAalifold program for predicting consensus RNA secondary structures.
  • Incorporating thermodynamic stability and sequence covariation into structure prediction.
