Posttranslational modifications in the CP43 subunit of photosystem II
(East Carolina University, 2002-11-12)
Photosystem II (PSII) catalyzes the light-driven oxidation of water
and the reduction of plastoquinone; the oxidation of water occurs at a cluster of four manganese. The PSII CP43 subunit functions in light ...
RDX and miRNA Expression: Zhang and Pan Respond
(East Carolina University, 2009-03)
The moderating effects of religiosity on the relationship between stressful life events and delinquent behavior
(East Carolina University, 2008)
Previous research has shown that many forms of strain are positively related to delinquency. Evidence also suggests that religiosity buffers the effects of strain on offending, but this issue requires further research. ...
Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)
Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ...
The evolution of parental care and egg size: a comparative analysis in frogs
(East Carolina University, 2006-03-22)
The evolution of parental care and egg size has attracted considerable attention and theoretical debate. Several different hypotheses have been proposed concerning the trajectories of parental care and egg size evolution ...
Molecular and Cellular Biology Animations: Development and Impact on Student Learning
(East Carolina University, 2005)
Educators often struggle when teaching cellular and molecular processes because typically they have only two-dimensional tools to teach something that plays out in four dimensions. Learning research has demonstrated that ...
Pleistocene glacial refugia across the Appalachian Mountains and coastal plain in the millipede genus Narceus: Evidence from population genetic, phylogeographic, and paleoclimatic data
(East Carolina University, 2009-01-30)
Background: Species that are widespread throughout historically glaciated and currently nonglaciated areas provide excellent opportunities to investigate the role of Pleistocene climatic change on the distribution of North ...
Functional Unit of the RNA Polymerase II C-Terminal Domain Lies within Heptapeptide PairsÂ
(East Carolina University, 2004-06)
Unlike all other RNA polymerases, the largest subunit (RPB1) of eukaryotic DNA-dependent RNA polymerase II (RNAP II) has a C-terminal domain (CTD) comprising tandemly repeated heptapeptides with the consensus sequence ...
Analyses of domains and domain fusions in human proto-oncogenes
(East Carolina University, 2009-03-17)
Background: Understanding the constituent domains of oncogenes, their origins and their fusions may shed new light about the initiation and the development of cancers. Results: We have developed a computational pipeline ...
Ancient Genome Duplications Did Not Structure the Human Hox-Bearing Chromosomes
(East Carolina University, 2001-05)
The fact that there are four homeobox (Hox) clusters in most vertebrates but only one in invertebrates is often cited as evidence for the hypothesis that two rounds of genome duplication by polyploidization occurred early ...
