Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...

MOTIVATION Similarity search is the foundation of bioinformatics. It plays a key role in establishing structural, functional and evolutionary relationships between biological sequences. Although the power of the similarity search has increased steadily in recent years, a high percentage of sequences remain uncharacterized in the protein universe. Thus, new similarity search strategies are neede...

String matching algorithm plays the vital role in the Computational Biology. The functional and structural relationship of the biological sequence is determined by similarities on that sequence. For that, the researcher is supposed to aware of similarities on the biological sequences. Pursuing of similarity among biological sequences is an important research area of that can bring insight into ...

results phylogenetic analysis of the partial ns5b region demonstrated the relatedness of isolate fsm165 to the new subtype reported from iran in 2006. moreover, some core/e1 and ns5b sequences that had a high level of similarity with fsm165 isolate were found through searching the hcv database. these sequences were previously either misclassified or could not be accurately classified. phylogene...

Recent years have witnessed an emergence of pattern discovery methodologies for solving numerous tasks which arise in computational biology. Known also as ``data mining'' approaches, they represent a novel approach for extracting useful information from databases containing various types of biological information. Initially, dynamic programming techniques were applied to the analysis of biologi...

objective: identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. methods: najdi cattle is the most prominent breeds in khuzestan province. to do this plan in shoushtar najdi cattle station, blood samples were taken from 15 najdi cattles. dna was extracted from wh...

MOTIVATION Redundant protein sequences in biological databases hinder sequence similarity searches and make interpretation of search results difficult. Clustering of protein sequence space based on sequence similarity helps organize all sequences into manageable datasets and reduces sampling bias and overrepresentation of sequences. RESULTS The UniRef (UniProt Reference Clusters) provide clus...
