MOSAIC software segments multiple DNA sequences into homogeneous zones by analyzing mutation patterns. This tool aids in understanding genomic regions, exemplified by yeast subtelomeric sequences.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • The MOSAIC software provides tools for DNA sequence analysis.
  • Available via anonymous FTP for research purposes.

Purpose of the Study:

  • To introduce MOSAIC, a novel tool for segmenting multiple aligned DNA sequences.
  • To demonstrate its application in identifying homogeneous zones based on mutation distributions.

Main Methods:

  • Utilizes a segmentation approach based on the distribution of mutational events.
  • Applies the method to analyze multiple aligned DNA sequences.

Main Results:

  • Successfully segmented aligned DNA sequences into distinct homogeneous zones.
  • Identified a specific repeated sequence in yeast subtelomeric regions.
