Noun1.genetic marker- a specific gene that produces a recognizable trait and can be used in family or population studies cistron,gene,factor- (genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well ...
Once a marker or a few markers are found to be associated with the trait in a given population, a dense molecular marker map in a standard reference population will help identify makers that are close to (or flank) the target gene. If a region is found associated with the desired traits...

Here we describe PICRUSt (phylogenetic investigation of communities by reconstruction of unobserved states), a computational approach to predict the functional composition of a metagenome using marker gene data and a database of reference genomes. PICRUSt uses an extended ancestral-state reconstruction ...

DNA, genetic, or molecular markers are known as clearly distinguishable DNA, gene or molecular sequences on specific locations on chromosomes. Introduction Mutations or alterations in genomic loci (positions on chromosome) lead evolutionary to polymorphisms (genetic variations) between species and individua...
Step 3: Comparison to Underlying Population Data Base Now that we have the two individual components in our recipe for ethnicity, a population reference set and your DNA results, we need to combine them. After DNA extraction, your individual results are compared to the underlying data base. Of...
Recent advances have made it possible to analyze high-throughput marker-gene sequencing data without resorting to the customary construction of molecular operational taxonomic units (OTUs): clusters of sequencing reads that differ by less than a fixed dissimilarity threshold. New methods control errors ...
In qRT-PCR data analysis, an internal reference gene is used to normalize the variation in input sample quantity. The relative quantification method used in current real-time qRT-PCR analysis fails to ensure data comparability pivotal in identification of prognostic biomarkers. By employing an ...
