Definition: The fundamental, physical, and functional unit of heredity Table of Contents Ageneis the fundamental, physical, and functional unit ofheredity. The genes make up the sequences of DNA (genotypes). The genotypes, together with the other factors (e.g. environmental factors), determine ...
Considering the central role that genes play in the understanding of biology, it is surprising that no single, simple definition of a gene exists. This is partly because genes are under multiple evolutionary constraints, and partly because the concept of a gene has both structural and functional ...

Because any given individual has two copies of each chromosome, each individual must have, by definition, two alleles for every marker. If identical alleles are inherited from each parent, individuals are homozygous for that marker. Markers are considered informative if there are sufficient alleles ...
Ashwini KumarSharma,RainerKönig, inSeminars in Cancer Biology, 2013 2.2Enrichment analysis Having set up the network as described above,gene set enrichmenttests can be employed to observe if subsets of this network show a changed regulation of cancer metabolism. It is to note that for these en...
High-definition spatial transcriptomics for in situ tissue profiling A dense, spatially barcoded bead array captures RNA from histological tissue sections for spatially resolved gene expression analysis. Sanja Vickovic , Gökcen Eraslan & Patrik L. Ståhl Article | 29 July 2019 scGen predicts...
predictions for arbitrary sequences, which enables the synthetic design of enhancers that are optimized to exhibit cell-type specificity31. Altogether, these advances and advantages open exciting avenues to study the expanding catalogs of genetic variants linked to disease and enhancer biology in ...
As omics progress, the legal definition of plant genetic resources appears more and more ambiguous, with a two-components: physical (e.g. seeds, propagules) and informational (DSI) (Aubry et al. 2022). This (possibly) new dichotomy has created obstacles for most fora dealing with genetic res...
Comparisons of differences and similarities in annotations, such as definition line (defline) gene descriptions, InterPro families, and Gene Ontology assignments, can be made with respect to the tree. The user can make a determination of whether the gene annotations are consistent with the tree to...
a significant deviation empirically by applying machine learning techniques to training and test sets of natural and synthetic sequences that we validated manually by sourcing them from sequence databases or from publications. Our definition is pragmatic and has limitations which reflect that we are ...
