|July 17, 2025
Summary
We introduce topological sequence analysis (TSA) for genome sequences, enabling efficient phylogenetic analysis. These novel methods offer a powerful new approach for analyzing complex sequential data.
Area of Science:
- Computational Biology
- Genomics
- Applied Mathematics
Background:
- Algebraic topology is effective for analyzing geometric and topological structures in point cloud data.
- The application of algebraic topology to genome sequence analysis is currently limited.
Purpose of the Study:
- To introduce novel topological sequence analysis (TSA) techniques for genome sequences.
- To develop methods for topological spectral analysis and phylogenetic analysis of genomic data.
Main Methods:
- Construction of $\Delta$-complexes and classifying spaces for genome sequences.
- Application of persistent homology and persistent path homology.
- Development of $\Delta$-complex-based persistent Laplacians for spectral analysis.
Main Results:
- Demonstrated the utility of TSA in phylogenetic analysis using Ebola virus and bacterial genomes.
- The proposed TSA methods are more efficient than existing k-mer topology approaches.
Conclusions:
- TSA provides an efficient and effective framework for analyzing genome sequences.
- TSA has potential applications in diverse fields such as linguistics, literature, music, media, and social sciences.

Evolutionary Relationships through Genome Comparisons
6.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
