BACKGROUND Biological sequences, such as proteins, have been provided with annotations that assign functional information. These functional annotations are associations of proteins (or other biological sequences) with descriptors characterizing their biological roles. However, not all proteins are fully (or even at all) annotated. This annotation incompleteness limits our ability to make sound ...

The clustering of biological sequence data is a significant task for biologists. The reason is that sequence clustering assists molecular biologists to group sequences based on the ancestral traits or hereditary information that are hidden in sequences. To accomplish the similarity detection and clustering tasks, several clustering algorithms, similarity and distance measures have been proposed...

In this study, the cDNA Growth Hormone (cGH) of the Belugasturgeon (Husohuso) and Russian sturgeon (Acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. The nucleotide sequence of the Beluga GH has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. The signal peptide cleav...

2.1.1 Biological Database Biological data are organized as a database of sequences. There are three types of biological sequences: Proteins, DNAs and RNAs. Large amounts of biological sequences are deposited in public databases. In recent years, the size of the biological database has doubled in every 15 or 16 months and in molecular biology, high-similarity search has become a basic operation ...

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...
