Spatial Distribution of Heterochromatin Bodies in the Nuclei of Triatoma infestans (Klug)
(2020-06-01)
Constitutive heterochromatin typically exhibits low gene density and is commonly found adjacent or close to the nuclear periphery, in contrast to transcriptionally active genes concentrated in the innermost nuclear region. ...
Short-range regulatory chromatin loops in plants
(Wiley Blackwell Publishing, Inc, 2020-04)
In all eukaryotic organisms, gene expression correlates with the condensation state of the chromatin. Highly packed genome regions, known as heterochromatins, are associated with repressed loci, whereas euchromatic regions ...
Long-range correlations in the mechanics of small DNA circles under topological stress revealed by multi-scale simulation
(Oxford Univ Press, 2016-11-02)
It is well established that gene regulation can be achieved through activator and repressor proteins that bind to DNA and switch particular genes on or off, and that complex metabolic networks determine the levels of ...
The status of platyrrhine phylogeny: A meta-analysis and quantitative appraisal of topological hypotheses
(Academic Press Ltd-elsevier Science Ltd, 2014-11)
Phylogenetic or species trees reflect the branching process of lineages and have direct and indirect interest for several branches of evolutionary anthropology. Estimating phylogenetic trees is a necessary first step toward ...
