Genetic Structure of Yonahlossee Salamander Populations.
… as conservation units. One mitochondrial DNA marker as well one nuclear DNA marker were amplified using polymerase chain reaction. After analysis, both markers show genetic differentiation suggesting geographic isolation. This information can be used by management agencies for the …

Molekulare Analysen zur Pluripotenz und Langzeitaktivität retroviral transduzierter hämatopoetischer Stammzellen
… Vektoren ist ein stabiler individueller DNA-Marker für jede transduzierte Zelle. Aus Leukozyten-DNA des Rhesusaffen wurden mehr als 80 Integrations-stellen durch ligationsmediierte PCRs identifiziert. Um aus dieser polyklonalen Population die Aktivität einzelner Stammzellklone direkt zu …

ANOMALIES ZERO and BRIGHTWOOD (Two Screenplays)
… Grant, must travel back in time to retrieve the DNA marker for immunity during The Great Visitation in London, 1665; her ultimate destination a small village, self-quarantined, just outside of London, known as Brightwood.</p>

Causal Gene Network Inference from Genetical Genomics Experiments via Structural Equation Modeling
… population is expression profiled and DNA marker genotyped. An Encompassing Directed Network (EDN) of causal regulatory relationships among genes can be constructed with eQTL mapping and selection of candidate causal regulators. Several eQTL mapping approaches and local structural …

Linkage studies of x-linked cleft palate and ankyloglossia in a British Columbia native kindred
… in the B.C. kindred which were initiated with DNA markers from the Xq21-q22 region and were later expanded to include markers from the Xq13 region. No recombination was observed between CPX and the DNA markers DXS447 (peak lod score [Zmax ] = 9.38), DXS72 (Zmax = 7.74; Gorski et al. 1992) and …

Factors that impact Pseudo-nitzschia spp. occurrence, growth, and toxin production
… present from 2009 Lugol’s-preserved L4 samples. DNA was successfully extracted and amplified from these samples which had been stored for up to 2 years. Initial sequence analysis identified the rbcL DNA marker as an informative site for future work with a number of L4 sequences closely relating …

Spatial structuring in trait variation in Polyommatus icarus in a functional context
… traits together with allozymes and a neutral DNA marker (AFLP) variation are studied here to understand how geographic trait variation is related to environmental variation. The approach adopted here is to study this along a latitudinal cline of temperature and photoperiod, using four …

Genomic and Phenotypic Analyses of Polychaete Sibling Species <i>Platynereis dumerilii</i> and <i>Platynereis massiliensis</i> in Relation to Ocean Acidification
… genetics by the amplification of a mitochondrial DNA marker (COI); (d) population genomics by a next-generation sequencing approach (RAD-seq); (e) background analyses and a long term laboratory experiment on selected genotypes/populations to study physiological responses to different pH …

Entwicklung neuer Markersysteme für die ancient DNA Analyse
… abgeleitet werden können. Die ancient DNA-Analytik bietet Zugang zu solchen biologischen Daten über die klassischen morphologischen Methoden hinaus. Zur Erweiterung der bislang verfügbaren Möglichkeiten der molekulargenetischen Untersuchung von Skelettfunden wurden im Rahmen der …

Genetic Characterization of Intermixed Walleye Stocks in Claytor Lake and the Upper New River, Virginia
… Fosters Falls. Using allozymes, microsatellite DNA, and mitochondrial DNA marker techniques to examine population structure of walleye, I determined that the walleye within Claytor Lake are a panmictic population. This is the result of years of stocking walleye from different genetic stocks and …

Is Alnus viridis 'a' glacial relict in the Black Forest ?
… ventured the extensive study of a chloroplast DNA-marker, to understand the evolutionary relationship between different populations of Green Alder (A. viridis) from the Black Forest and the European Alps. Looking at the photomorphogenesis as an indicative trait to test, whether the divergence …

DNA barcoding of forensically important flies in the Western Cape
… is damaged. Molecular identification such as DNA barcoding has therefore become a popular method of identifying species. DNA barcoding characterises species by sequencing and analysing specific regions in the genome. This technique has been used to characterise species in various countries …

Linkage fine-mapping, GWAS and QTLs affecting morpho-agronomic traits of a common bean RIL population
… An auxiliary tool in plant breeding is the DNA marker-assisted selection. Linkage mapping (LM) is the most common approach to detect molecular markers associated to quantitative trait loci (QTL). The abundance of molecular markers in the genome of the species made of association mapping (AM) …

Diachonic DNA Analyses of Animal Breeds and Populations
… breed conservation choices. Utilising ancient DNA data could potentially permit detailed diachronic analyses of the development of animal breeds. Ancient DNA analyses have typically focussed on large-scale biogeographic patterns in time and space, such as the spread of domesticates or the …

High-resolution mapping of abasic sites and pyrimidine modifications in DNA
… for the growth and survival of cells. Cellular DNA is constantly subject to both endogenous and exogenous sources of damage, leading to the formation of damage products. Abasic sites occur when a nucleobase is lost from DNA by hydrolysis and can lead to mutations and genomic instability. This …

Multidisciplinary investigation into stock structure of small pelagic fishes in southern Africa
… seven microsatellite loci and the mitochondrial DNA marker, ND2, were used to supplement existing information on sardine. Otolith shape, while influenced by fish length and season of capture, distinguished the east coast samples from those taken elsewhere, while the otolith elemental signatures …

Evaluation of insertion / deletion polymorphisms (INDELs) applied to forensic casework in Malaysia
… are up to 200 bp. The percentage of recovery DNA profile from degraded DNA using mtDNA is much higher due to its present in cells at a much higher copy number than the nuclear DNA. However, the major drawback for mtDNA is labour intensive and has a low information value (i.e. it is not highly …
