The paper puts forward a new graphical representation of DNA sequences -- H curve, gives the definition of H curve and the relationship between H curves and represents mitochondrial DNA sequences by H curve for the first time. Through calculating the distance of H curve compressed to get the distance matrix of mitochondrial DNA of eight species, then use Kruskal algorithm to construct the DNA sequence...
Data-mining over software can reveal similar patterns on software code. This can give important insights for the design of hardware cores, especially considering the benefits of the merge of software kernels and their implementation as a single hardware core. However, software codes have characteristics that make inadequate the direct use of typical data mining tools, mainly related to their large...
Objective: To establish a practical, accurate and convenient DNA molecular genetic marker technique for the identification of Testudinis Carapax et Plastrum. Methods: The mtDNA were extracted from Testudinis Carapax et Plastrum and its adulterants by salting-out method respectively. Bioinformatics technology was used to explore the identification and characterization of mitochondrial cytobchrome b...
The Rank Distance is a relatively new metric being used in genomic applications that has good potential, excellent computational properties and known limitations. This paper proposes a refinement to the standard Rank Distance in order to overcome some principal limitations of the metric for genetic applications. The paper first gives an introduction into the main concepts of the Rank Distance, then...
AFLP technique was used to elucidate systematic relationships among 26 cultivars of Tree Peony. Six AFLP primer combinations (M+3 and P+3) were used to produce recognizable 757 bands, among which 623 bands are polymorphic. The percentage of polymorphic bands was 82%, suggesting abundant genetic diversity among sect. Moutan. Clustering analysis showed that some cultivars of dwarf and tall peony types...
An inductive domestication method for removing SO2 from tail gas contained SO2 were set up. A group of desulfuration bacterium are obtained with this method domesticating the bacterium in oxidation ditch of city sewage treatment plant over 6d with low concentration SO2 gas. The desulfuration bacterium have an ability with biodegradation rate of 600 mg(SO32−)/(L.h) during 0.5h, and degradation efficiency...
Recent advances in molecular sequencing technology have given rise to novel algorithms for simultaneously aligning short sequence reads to reference sequence alignments and corresponding evolutionary reference trees. We present a complete hardware/software implementation for the acceleration of a program called PaPaRa, a newly introduced dynamic programming algorithm for this purpose. We verify the...
The microbial communities in 6 nightsoil sludge samples taken from the beginning and the 8th days of the 3 anaerobic digestion reactors, ie. the original nightsoil sludge (A), adding 0.0075% HBH-II (B) and adding 0.075% HBH-II under initial pH 10(C), were studied using PCR-DGGE technique. The result shows that alkaline pretreatment can change the microbe community structure of nightsoil sludge system...
Mahseer being the most important freshwater fish that contributes to the major fisheries activity of the rivers in the world. In Malaysia, Mahseer is an important indigenous freshwater fish because of their market value. However, the number of this freshwater fish declining from day to day due to the human activity and environment destruction. In this study, mitochondrial DNA (mtDNA) which is cytochrome...
On the basis of the systematic investigation of manganese tolerating plants which grew in Xiangtan manganese tailings, rhizosphere soils of Chenopodium album Linn were collected. 1 yellow manganese-resistant strain numbered XY was isolated from the rhizosphere of fresh plant through concentration gradient screening technique, and the cellular form, physiological and biochemical tests were conducted,...
Phylogenetic data arising on two possibly different tree topologies might be mixed through several biological mechanisms, including incomplete lineage sorting or horizontal gene transfer in the case of different topologies, or simply different substitution processes on characters in the case of the same topology. Recent work on a 2-state symmetric model of character change showed that for 4 taxa,...
