JaDis

JaDis computes evolutionary distances between nucleic acid sequences and analyzes G+C base frequencies to quantify evolutionary divergence and compare coding and non-coding regions.

Key Features:

• Evolutionary distance calculation: Computes evolutionary distances between nucleic acid sequences that quantify divergence and reflect phylogenetic relationships.
• G+C base frequency analysis: Measures G+C base frequencies to assess genomic composition and stability.
• Sequence-type comparisons: Supports comparisons of coding sequences, non-coding sequences, or combinations of coding and non-coding sequences.
• Detailed comparative outputs: Provides quantitative metrics for detailed comparison across different types of genetic material.

Scientific Applications:

• Molecular evolution: Quantifies evolutionary divergence and sequence variation for studies of molecular evolution.
• Comparative genomics: Compares coding and non-coding regions across genomes to investigate conservation and genomic architecture.
• Identification of conserved non-coding elements: Aids detection of conserved non-coding regions that may have regulatory roles.
• Genomic composition analysis: Uses G+C frequency profiles to study genomic composition, stability, and implications for gene expression regulation and genome evolution.
• Functional evolution of coding sequences: Elucidates evolutionary patterns in coding sequences that may correlate with functional adaptations.

Methodology:

Implemented as a Java application that computes evolutionary distances between nucleic acid sequences and analyzes G+C base frequencies.
