Viral hemorrhagic septicemia virus (VHSV) is an enveloped non-segmented, single-stranded, negative-sense RNA virus that Viral hemorrhagic septicemia virus (VHSV) is an enveloped non-segmented, single-stranded, negative-sense RNA virus that belongs to the Novirhabdovirus genus of the family  Rhabdoviridae. This virus causes economically significant diseases of farmed rainbow trout, in Turkey, wh...

heat shock proteins (hsps), are highly important due to their association with such economically important traits in animals as resistance to temperature shock and mastitis. in the current study, to get a comprehensive information on molecular structure and evolution of the hsp70s, and the available hsp70 sequences of the cattle and other animals taken from ncbi and aligned together. then, nucl...

Nucleotide sequences coding for the N- and C-terminus of the A subunit and the N-terminus of the B subunit of cholera toxin were determined. These results show that the genes for the A and B subunits overlap out of phase by one nucleotide and that each subunit is synthesised as a precursor molecule which is subsequently processes after translation. It is proposed that the synthesis of each subu...

Recombination between viral and cellular genes can give rise to new strains of retroviruses. For example, Rous-associated virus 61 (RAV-61) is a recombinant between the Bryan high-titer strain of Rous sarcoma virus (RSV) and normal pheasant DNA. Nucleic acid hybridization techniques were used to study the genome of RAV-61 and another RAV with subgroup F specificity (RAV-F) obtained by passage o...

Esox lucius is an economically important freshwater species. Mitochondrial cytb, 12SrRNA, and 16SrRNA gene sequences were used in order to clarify the genetic variation and population structure in three E. Lucius populations, i.e., one Wild population (W) and two hatchery populations (Hatchery Population I-HPI and Hatchery Population II-HPII). A total of 55 individuals, with 19 from wild and 1...

A statistical method was developed for reconstructing the nucleotide or amino acid sequences of extinct ancestors, given the phylogeny and sequences of the extant species. A model of nucleotide or amino acid substitution was employed to analyze data of the present-day sequences, and maximum likelihood estimates of parameters such as branch lengths were used to compare the posterior probabilitie...

FAN is a server for fingerprint analysis of nucleotide sequences. The server performs a search of submitted nucleotide sequences against the PRINTS database. Searches are performed directly against fingerprints using a codon position specific score matrix (PSSM) approach. The advantages of this approach are increased specificity for coding sequence (CDS) over non-CDS, and increased tolerance to...
