Applications of nanotechnology and nano-science have ever-expanding breakthroughs in medicine, agriculture and industries in recent years; therefore, synthesis of metals nanoparticle (NP) has special significance. Synthesis of NPs by chemical methods are long, costly and hazardous for environment so biosynthesis has been developing interest for researchers. In this regard, the extracellular biosynthesis...
We propose a signal processing approach for detecting enrichment regions from ChIP-seq datasets. A wavelet transform of the ChIP-seq data offers a direct visualization for both short- and long-range patterns of the genome-wide mapping profile for protein binding site on DNA. To investigate the location of transcription factor binding site (TFBS) from ChIP-seq data, a wavelet-based peak detection algorithm...
The strands of chromosomes are supposed to be split into genic and intergenic regions. Gene identification is an optimization problem in Eukaryotic DNA splicing. An optimal solution is essential which may help in better protein translation. We have proposed a novel approach for gene identification by employing discrete wavelet transforms for noise reduction in DNA sequences and introducing a new indicator...
Currently, the size of biological databases has increased significantly with the growing number of users and the rate of queries where some databases are of terabyte size. Hence, there is an increasing need to access databases at the fastest possible rate. Where biologists are concerned, the need is more of a means to fast, scalable and accuracy searching in biological databases. This may seem to...
The partial sequence of the psbA gene from Cladosiphon okamuranus was amplified by PCR and their sequences were analysed. Neighbor-joining method was used to build phylogenetic trees according to the psbA sequence among 11 species, C. okamuranus included, that are affiliated to the algal order Ectocarpales. The results showed that the nucleotide sequence is 737 bp and the sequence shares high homology...
We determined the nucleotide sequence of a portion of the duck enteritis virus (DEV) strain CHv which was suspected to be the UL10 gene(GenBank accession no EU195100.), encoding glycoprotein M(gM). The UL10 gene was cloned and sequenced, which was composed of 1230 nucleotides encoding 409 amino acids, with a predicted molecular mass of 45.752 kDa. We calculated the codon usage bias in the newly identified...
The glycoprotein I (gI) gene homologue of duck plague virus (DPV) was cloned by degenerate polymerase chain reaction (PCR) and sequenced. DPV gI gene open reading frame (ORF) was 1116 bp in length and its primary translation product was a polypeptide of 371 amino acids long. Comparison with other herpesvirus revealed higher similarity, had a close evolution relationship with members of the genus Mardivirus...
β-ketoacyl-ACP synthetase II (KAS II) which catalyzes the elongation of 16:0-ACP to 18:0-ACP, determines the ratio of palmitic acid (16:0) to stearic acid (18:0). Using Rapid Amplification of cDNA Ends (RACE) and a peanut cDNA library we had previously constructed, we isolated a 1867bp cDNA of the KAS II gene containing a 1212bp complete open reading fragment (ORF). Sequence analysis revealed that...
Kosteletzkya virginica is a halophyte species which could be used for production of industrial raw material such as biodiesel and for developing ecologically sound saline agriculture as well as for tideland soil improving. Using Rapid Amplification of cDNA Ends (RACE) method, a 1610 bp cDNA of stearoyl-ACP desaturase (SAD) gene containing a 1188 bp complete open reading fragment (ORF) was firstly...
Abstract-An open reading frame (ORF) containing 675 nucleotides was got by sequencing the DEV gene libraries constructed by our laboratory. The ORF was identified as DEV UL45 gene by aligning with gene bank database using the software of BlastN and ORF Finder. Specific primers were designed and PCR products containing this ORF were cloned into the vector of PMD18-T. Dot blot confirmed the UL45 gene...
cDNA containing the 3' part sequences of seven Lily symptomless virus (LSV) isolates were obtained by RT-PCR and sequenced. The sequenced region is corresponding to partial CP gene and the entire sequences of 16kDa gene located at the 3' end of LSV genome. The sequence homologies of partial CP and 16 kDa protein genes, compared with other reported isolates, were 87.4% to 100% and 97.9% to 100% respectively...
Pear is a commercially important fruit tree widely distributed in China that displays GSI (gametophytic self-incompatibility). It is necessary to determine S-alleles and S-genotypes for clarifying the compatibility between cultivars prior to pear planting and breeding. The S-genotype analysis using conventional method of artificial pollination is time consuming and requires much labor. In addition,...
We present a global clustering approach to identify putative intergenic non-coding RNAs based on the RNA polymerase II and Histone 3 lysine 4 trimethylation signatures. Both of these signatures are processed from the digital sequencing tags produced by chromatin immunoprecipitation, a high-throughput massively parallel sequencing (ChIP-Seq) technology. Our method compares favorably to the comparison...
This paper is an attempt to highlight the fundamental approaches, algorithms and techniques being employed in interesting areas of Computational Biology. The comparative analysis of genomic sequences, micro-array technology, phylo-genetic tree, alignment matters, maximum sequence search and protein structure prediction are some of NP hard problems. There has been no direct solution proposed so far...

Eukaryotic transcriptional regulation is complex. Typically, it takes place by cooperative regulation. A number of studies have characterized this aspect in the upstream promoter sequences of Saccharomyces cerevisiae genes. In this paper, we performed an analysis of co-occurrence of motifs in introns. Here, we first conducted a Match™ program to detect single motifs for transcriptional factors. Second,...
The pattern of genome transcription in prokaryotes is determined by selective distribution of RNA polymerase within the genome. The gene selectivity of RNA polymerase is modulated after interaction with DNA-binding transcription factors (TFs). Escherichia coli contains a total of about 300 TFs, but the regulatory function has not yet been identified for about one third. For quick and systematic search...
With the advancement of biological techniques, researches in the fields of marine evolution, ecology, and aquaculture have an explosive increasing rate both in volume and diversity. More than tens of thousands of genomic sequences were available for important marine species. However, most of the structures and corresponding functions remain unresolved and unknown. To discover the biological characteristics...
With the increase of sequence information, many methods have been used in detecting sequence similarities. In order to avoid the shortcomings of the traditional method based on sequences alignment such as high time and space complexity, component vector method has been successfully used in the reconstruction of phylogenetic tree using genome (proteome) or conserved molecular sequences. With the aim...
A filtering technique for the location of hot spots in proteins proposed recently is applied for the location of exons in DNA sequences. The technique involves conversion of a DNA character sequence into a numerical sequence using the electron-ion interaction potential values and then filtering the numerical sequence using a narrowband bandpass digital filter whose passband is centered at the period-3...
