Modern Molecular Taxonomy

Modern Molecular Taxonomy

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

Main Methods:

The Rubber Band Technique: Location Base (RBT-L) algorithm was developed, inspired by the physical behavior of a rubber band.
RBT-L is an iterative optimization approach designed to find optimal alignments.
The algorithm was tested using the BALiBASE 2.0 benchmark dataset, a standard for evaluating MSA methods.

Main Results:

RBT-L demonstrated superior performance compared to existing methods on the BALiBASE 2.0 benchmark.
The technique proved effective even when applied to difficult and evolutionarily distant protein sequences.
The results indicate a significant improvement in alignment accuracy.

Conclusions:

The proposed Rubber Band Technique: Location Base (RBT-L) presents a novel and effective solution for the Multiple Sequence Alignment problem.
RBT-L offers a promising advancement in bioinformatics tools for analyzing protein sequence data.
