In biology, a kingdom (Latin: regnum, plural regna) is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla. Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia, Plantae, Fungi, Protista,...
rigor, and reproducibility [7]. In a recent report, we examined the top 25 most cited papers in several domains of behavioral neuroscience in which previously documented significant time-of-day effects
alignment or "supermatrix" approaches have been used to propose deep phylogenetic relationships for all three domains of life [6–9]. Another class of approaches used to infer genomic relationships are based on the abstraction of genes as a set of binary presence/absence criteria. Phylogenetic prof...
which requires integration of endogenous and environmental signals into fine-tuned spatial/temporal gene expression in a stable micro-environment. Biomolecular condensates formed by protein phase separation have been demonstrated as a new strategy for many cellular functions in yeast and animal...
Chapters 23 & 24 Bacteria and Viruses Classification & Diversity of LifeStandard 7: Students shall demonstrate an understanding that organisms are diverse. CDL.7.B.1 Differentiate between the domains Bacteria & Archaea.CDL.7.B.2 Differentiate the characteristics of these kingdoms — Eubacteria & ...
The success of genome-scale models (GEMs) can be attributed to the high-quality, bottom-up reconstructions of metabolic, protein synthesis, and transcriptional regulatory networks on an organism-specific basis. Such reconstructions are biochemically, gen
(known as the ‘histone code’) and define dynamic transitions between active and silent chromatin states that co-regulate important biological processes [3]. PTMs occur primarily on the N-terminal tails of histones but also on their globular domains and their C-termini, and include methylation,...
Learn about theterminology of biology. This chart shows how the words used in biology are formed. They have meanings. Read about the “Study of Life.” Over the next few days you will look more closely at the characteristics of life. For today, think about what youalreadyknow about living...
Sjögren syndrome/scleroderma autoantigen 1 (SSSCA1) was first described as an auto-antigen over-expressed in Sjögren’s syndrome and in scleroderma patients. SSSCA1 has been linked to mitosis and centromere association and as a potential marker can
Plant somatic cells reprogram and regenerate new tissues or organs when they are severely damaged. These physiological processes are associated with dynamic transcriptional responses but how chromatin-based regulation contributes to wound-induced gene ex
