We refined entropy theory to analyze nucleic acid and protein sequences, identifying key genomic positions. This method aids in understanding genome function and detecting mutation hotspots in coding and non-coding regions.

Area of Science:

  • Bioinformatics
  • Genomics
  • Computational Biology

Background:

  • Entropy theory provides insights into sequence data but requires refinement for broader applications.
  • Analyzing both coding and non-coding regions (NCRs) is crucial for a comprehensive understanding of genome function.
  • Identifying functionally important genomic positions can guide mutagenesis studies.

Purpose of the Study:

  • To refine entropy theory for convenient analysis of nucleic acid and protein sequence data.
  • To develop a method for analyzing both coding and non-coding regions without considering selection constraints.
  • To identify genomic positions with maximal entropy as potentially crucial for genome function.

Main Methods:

  • Refined entropy theory applied to sequence data.

  • Analysis focused solely on sequence data, excluding selection constraints.
  • Method validated on coding and non-coding regions of Classical Swine Fever Virus (CSFV) strains.

    • Main Results:

    • Maximal entropy positions may indicate critical roles in genome function.
    • The method is effective for analyzing complete genomes.
    • Sensitive positions for mutagenesis can be detected.

    Conclusions:

    • The refined entropy theory offers a new approach to sequence analysis.
    • This method is applicable to both coding and non-coding regions.
    • The approach provides a basis for elucidating functional mechanisms and guiding mutagenesis.
